Reasoning has a shape: a cause ('because the road was icy'), a result ('so we were late'), and sometimes a purpose ('in order to be safe'). Ukrainian marks each of these with its own connectors, and the single most useful thing to get right is the pair тому́ and тому́ що — they look almost identical but point in opposite directions. тому́ alone means 'therefore, that's why' (it introduces the result); тому́ що means 'because' (it introduces the cause). On top of the everyday markers, Ukrainian has one connector with no clean English equivalent — адже́, a justifying 'after all / since' that introduces a reason the listener is assumed to already know.
Cause: тому́ що, оскі́льки, че́рез це, бо
To introduce a reason, Ukrainian's neutral workhorse is тому́ що ('because'). оскі́льки means 'since, given that' and leans formal — it often opens a sentence, foregrounding a reason already shared with the reader. бо is the light, conversational 'because, for' — but it has a hard rule: бо cannot start a sentence; it only joins a reason after the main clause (see subordinating conjunctions of time and cause). For 'because of this' as a sentence connector pointing back at a whole situation, use че́рез це (че́рез + accusative = 'because of, on account of').
| Connector | Meaning | Register / note |
|---|---|---|
| тому́ що | because | neutral, the default |
| бо | because, for | conversational; can't open a sentence |
| оскі́льки | since, given that | formal; often opens the sentence |
| че́рез це | because of this | points back at a whole situation |
| адже́ | after all, since (justifying) | introduces a known supporting reason |
Я не прийшо́в на пра́цю, тому́ що захворі́в.
I didn't come to work, because I fell ill. (тому́ що — the neutral 'because'.)
Оскі́льки всі вже зі́бралися, мо́жемо почина́ти.
Since everyone's already here, we can start. (оскі́льки opens with a shared reason; formal-leaning.)
Доро́ги обледені́ли. Че́рез це бага́то рейсі́в скасува́ли.
The roads iced over. Because of this, many flights were cancelled. (че́рез це points back at the whole situation.)
Ляга́й спа́ти, бо за́втра ра́но встава́ти.
Go to bed, because you have to get up early tomorrow. (бо — conversational 'because', after the main clause; it could never open the sentence.)
The justifying адже́ — Ukrainian's 'after all'
адже́ deserves its own section, because it has no tidy English match. It introduces a reason the speaker treats as already known or self-evident — a justification offered in support of the claim just made, with the flavour of 'after all, you know, as you're aware'. Where тому́ що answers a neutral 'why?', адже́ says 'and the reason — which you'll recognise — is this'. It's a favourite in argument and explanation, and it often carries a faintly persuasive or reassuring tone.
Він упо́рається — адже́ це його́ фах.
He'll manage — after all, it's his profession. (адже́ supplies a reason the listener already accepts.)
Не хвилю́йся за квито́к, адже́ ми забронюва́ли його́ ще тиждень тому́.
Don't worry about the ticket — after all, we booked it a week ago. (адже́ reassures with a known fact.)
Зві́сно, вона́ зрозумі́є, адже́ ви да́вні дру́зі.
Of course she'll understand — after all, you're old friends. (адже́ justifies the claim with shared knowledge.)
Result: тому́, о́тже, таки́м чи́ном, в результа́ті, тож
To introduce an outcome, the everyday word is тому́ ('that's why, therefore') — it states the result that follows from a cause. о́тже means 'so, thus, consequently' — it draws a logical conclusion and is a touch more bookish, a favourite for ending a reasoning chain ('so, in short, …'). таки́м чи́ном is the formal 'thus, in this way', common in writing and presentations. в результа́ті means 'as a result', and тож is a light, conversational 'so' that opens a consequence. All of these are comma-set sentence connectors when they lead.
| Connector | Meaning | Register / flavour |
|---|---|---|
| тому́ | therefore, that's why | neutral, everyday |
| тож | so | conversational |
| о́тже | so, thus, consequently | draws a conclusion; slightly bookish |
| таки́м чи́ном | thus, in this way | formal / written |
| в результа́ті | as a result | neutral-formal |
Лі́фт не працю́є, тому́ доведе́ться йти схо́дами.
The lift isn't working, so we'll have to take the stairs. (тому́ — 'therefore, that's why', introducing the result.)
Усі́ да́ні збіга́ються. О́тже, гіпо́теза підтве́рджується.
All the data line up. So the hypothesis is confirmed. (о́тже — draws a logical conclusion.)
Ми скороти́ли ви́трати й знайшли́ нови́х кліє́нтів. Таки́м чи́ном компа́нія ви́жила.
We cut costs and found new clients. In this way the company survived. (таки́м чи́ном — formal 'thus, in this way'.)
По́їзд відмени́ли. Тож ми ви́рішили взя́ти авто́.
The train was cancelled. So we decided to take the car. (тож — conversational 'so'.)
Purpose: для цьо́го, з ціє́ю мето́ю
To say 'for this purpose' as a connector pointing forward to an aim, Ukrainian uses для цьо́го ('for this') and the more formal з ціє́ю мето́ю ('with this aim, to this end'). These bridge from a stated goal to the steps that serve it. (For full purpose clauses with щоб / для то́го щоб 'in order to', see subordinating conjunctions of condition and purpose.)
Ми хо́чемо ви́йти на нови́й ри́нок. Для цьо́го наймемо́ місце́ву кома́нду.
We want to enter a new market. For this, we'll hire a local team. (для цьо́го — bridges from goal to means.)
Уря́д пла́нує зни́зити безробі́ття. З ціє́ю мето́ю запуска́ють нові́ програ́ми.
The government plans to cut unemployment. To this end, new programmes are being launched. (з ціє́ю мето́ю — formal 'with this aim'.)
Wrapping up: підсумо́вуючи, одни́м сло́вом
To conclude or sum up, Ukrainian reuses some result connectors and adds dedicated ones. о́тже and таки́м чи́ном both serve as 'so, in conclusion'. підсумо́вуючи ('to sum up, summarising') is the explicit wrap-up gerund. одни́м сло́вом means 'in a word, in short' — it signals that a tidy summary is coming.
Підсумо́вуючи, прое́кт удали́й, але́ потребу́є доро́бки.
To sum up, the project is a success, but it needs some finishing work. (підсумо́вуючи — explicit wrap-up.)
Спі́знення, загу́блений бага́ж, зі́псована пого́да — одни́м сло́вом, по́дорож не вда́лася.
Delays, lost luggage, ruined weather — in a word, the trip was a flop. (одни́м сло́вом — 'in short', before a summary.)
Source-language comparison
For an English speaker, the headline is the тому́ / тому́ що split: English so and because are obviously different words, but in Ukrainian the result word (тому́) and the cause word (тому́ що) share a stem, so it's easy to drop the що and accidentally say 'therefore' when you mean 'because'. Keep the arrow straight: cause тому́ що, result тому́. Second, English has nothing quite like адже́ — the closest is 'after all' or 'seeing as', but адже́ is more grammaticalised and far more frequent; learn to deploy it when you justify a claim with shared knowledge. Third, remember бо can't open a sentence — a hard structural rule with no English parallel.
For a Russian speaker: use the Ukrainian connectors — тому́ що, оскі́льки, адже́, тому́, о́тже, таки́м чи́ном, тож — and mind the stress (тому́, о́тже, таки́м чи́ном) and the letter і (оскі́льки). The justifying particle in адже́ overlaps the emphatic же; for that, see emphatic particles.
Common Mistakes
❌ Я не прийшо́в, тому́ захворі́в.
To say 'because' you need тому́ ЩО — bare тому́ means 'therefore'. As written this reads 'I didn't come, therefore I fell ill', the wrong arrow.
✅ Я не прийшо́в, тому́ що захворі́в.
I didn't come, because I fell ill.
❌ Бо доро́га обледені́ла, ми спізни́лися.
бо can't open a sentence. Lead with the main clause, or use оскі́льки: Оскі́льки доро́га обледені́ла, ми спізни́лися.
✅ Ми спізни́лися, бо доро́га обледені́ла.
We were late, because the road iced over.
❌ Усі́ да́ні збіга́ються, тому́ що гіпо́теза підтве́рджується.
This is a CONCLUSION, not a reason — use о́тже / тому́ (result), not тому́ що (cause): …збіга́ються. О́тже, гіпо́теза підтве́рджується.
✅ Усі́ да́ні збіга́ються. О́тже, гіпо́теза підтве́рджується.
All the data line up. So the hypothesis is confirmed.
❌ Лі́фт не працю́є, отже доведе́ться йти схо́дами.
When you lead a sentence with the parenthetical о́тже, set it off with a comma: …не працю́є. О́тже, доведе́ться… (or simply use тому́ to join the clauses).
✅ Лі́фт не працю́є, тому́ доведе́ться йти схо́дами.
The lift isn't working, so we'll have to take the stairs.
Key Takeaways
- Cause: тому́ що ('because', default), оскі́льки ('since', formal, often opens), че́рез це ('because of this'), бо ('because', conversational — never opens a sentence).
- адже́ is the distinctly Ukrainian justifying 'after all / since' — a reason the listener already accepts (Він упо́рається — адже́ це його́ фах).
- Result: тому́ ('therefore, that's why'), о́тже ('so, thus' — draws a conclusion), таки́м чи́ном ('thus', formal), в результа́ті ('as a result'), тож ('so', conversational).
- тому́ (result) vs тому́ що (cause) is the make-or-break contrast — the same stem, opposite directions.
- Purpose / conclusion: для цьо́го / з ціє́ю мето́ю ('for this / to this end'), підсумо́вуючи ('to sum up'), одни́м сло́вом ('in a word').

- Connectors of Addition and SequenceB1 — Discourse connectors that add and sequence ideas in Ukrainian writing and speech: addition (тако́ж / теж 'also', крім то́го 'besides', до то́го ж 'moreover', бі́льше то́го 'what's more', не ті́льки… а й 'not only… but also') and sequence (по-пе́рше / по-дру́ге / по-тре́тє 'firstly/secondly/thirdly', споча́тку 'at first', по́тім / да́лі 'then/next', наре́шті / зре́штою 'finally', відта́к, вре́шті-решт) — the fixed chunks that structure a coherent paragraph, with written vs spoken register and the commas they need.
- Connectors of Contrast and ConcessionB1 — The Ukrainian toolkit for marking that two ideas clash: contrast connectors (одна́к / проте́ 'however', натомі́сть 'instead', з одного́ бо́ку… з і́ншого бо́ку 'on one hand… on the other', а 'whereas') and concession (все ж / все-та́ки 'still', тим не ме́нш 'nonetheless', незважа́ючи на це 'despite this', хоча́ 'although'), plus the counter-expectation pair наспра́вді 'actually' and навпаки́ 'on the contrary' — and the key insight that written Ukrainian keeps the inter-sentential 'however' (одна́к, проте́) distinct from the clause-internal 'but' (але́, а).
- Subordinating Conjunctions: Time and CauseA2 — The subordinators that attach a when-clause or a why-clause, each with an OBLIGATORY comma before it. Time: коли́ 'when' (future after коли́ for future reference — Коли́ закі́нчу, відпочи́ну, both future!), по́ки/до́ки 'while/until', як ті́льки 'as soon as', пі́сля то́го як 'after', перш ніж / пе́ред тим як 'before', відто́ді як 'since'. Cause: бо 'because' (everyday, never starts a sentence), тому́ що (slightly more formal), оскі́льки 'since', че́рез те що, завдяки́ тому́ що 'thanks to'; тому́ alone = 'therefore'.
- Subordinating Conjunctions: Condition, Purpose, ConcessionB1 — Three families of subordinators that English collapses or marks only with verb forms. CONDITION: якщо́ 'if' for real/likely conditions (with the FUTURE — Якщо́ бу́де дощ, залиши́мося вдо́ма) versus якби́ 'if' for hypotheticals (with PAST + би/б — Якби́ був дощ, ми б залиши́лися). PURPOSE: щоб 'so that / in order to', + infinitive for the same subject, + past form for a different subject; also для то́го щоб, аби́. CONCESSION: хоч/хоча́ 'although', незважа́ючи на те що 'despite', дарма́ що, хай/нехай 'even if'. Comma before the subordinator.
- Emphatic Particles (Же/Ж, Таки́, Аж, Наві́ть, Тільки)B1 — The high-frequency emphatic and focus particles that carry attitude English marks with stress or words like 'after all / even / just'. же/ж (ж after a vowel) 'after all / then / indeed', enclitic, sits second (Що ж роби́ти?, Ти ж обіця́в!). таки́ 'still / after all / indeed' (Він таки́ прийшо́в). аж 'as much as / all the way / even' (аж до Ки́єва, аж три ра́зи). наві́ть 'even'. ті́льки/лише́/лиш 'only / just'. саме́ 'exactly'. -бо/-но urge a command (Іди́-бо!, скажи́-но). Peppering speech with these is what makes Ukrainian sound native; же/ж especially is ubiquitous and almost untranslatable.
- Managing Topics and TurnsB2 — The fixed phrasal markers that organize a longer stretch of Ukrainian discourse: introducing a topic (щодо́ / стосо́вно + genitive 'as for / regarding', що ж до… 'as far as … is concerned'), shifting and digressing (до ре́чі / між і́ншим 'by the way', до сло́ва 'speaking of', а втім 'though'), returning (поверта́ючись до… 'returning to', о́тже), reformulating (тобто́ 'that is', іна́кше ка́жучи 'in other words', точні́ше 'more precisely', вла́сне ка́жучи 'as a matter of fact'), and closing (коро́тше ка́жучи 'in short', одни́м сло́вом 'in a word', підсумо́вуючи 'to sum up', зага́лом 'all in all') — with the key insight that щодо́ / стосо́вно govern the genitive.
