When you want to glue a cause to its consequence across two sentences — "It's raining; that's why I'm staying in" — Romanian gives you a set of markers that all express the same causal link but point in two opposite directions. Some markers state the cause first and then point forward to the result (de aceea "that's why," așa că "and so," ca urmare "as a result"). Others sit on the cause itself and point backward (pentru că "because"). The link is identical — A causes B — but where you stand and which way you face differs, and getting that direction wrong is the single most common learner slip in this area. This page sorts the result-pointing markers by register and pins down the de aceea vs pentru că contrast that trips up almost every English speaker.
de aceea / de asta: "that's why"
de aceea (literally "because of that") and its more colloquial twin de asta ("because of this") are the everyday "that's why / for that reason." You state the cause, then de aceea introduces the consequence. The marker points forward: what follows it is the result.
Plouă, de aceea rămân acasă.
It's raining, that's why I'm staying home. (cause first → de aceea + result)
N-am dormit deloc azi-noapte. De asta sunt așa de morocănos.
I didn't sleep at all last night. That's why I'm so grumpy. (de asta = colloquial 'that's why')
Trenul avea întârziere; de aceea am ratat ședința.
The train was delayed; that's why I missed the meeting.
The register split is clean: de aceea is neutral and works everywhere; de asta is (informal), at home in casual speech and texting.
din cauza asta: "because of that"
din cauza asta ("because of that, on account of that") is close to de aceea but slightly heavier and more explicitly causal — it literally names "the cause." It often carries a faintly negative coloring, since cauză ("cause") frequently attaches to problems and bad outcomes; for a positive cause, Romanians lean toward datorită ("thanks to") in the phrasal version. Like de aceea, it states the cause first and points forward to the result.
S-a stricat liftul. Din cauza asta urc pe scări de o săptămână.
The lift broke down. Because of that I've been taking the stairs for a week.
A băut prea multă cafea și din cauza asta n-a putut adormi.
He drank too much coffee, and because of that he couldn't fall asleep.
așa că: the spoken "and so"
așa că ("so, and so, therefore") is the most natural conversational way to draw a consequence in the flow of speech. It welds the two parts into one breath — "It was late, so we went home." It's the spoken workhorse here, looser and more frequent in talk than the formal connectors below.
Era deja închis, așa că ne-am întors a doua zi.
It was already closed, so we came back the next day.
N-aveam bani de taxi, așa că am mers pe jos.
We didn't have money for a taxi, so we walked.
ca urmare / drept urmare / prin urmare: the formal "consequently"
For careful, written, or official prose, Romanian uses the heavier consequence markers. ca urmare and drept urmare ("as a result, in consequence") foreground the result as the outcome of what was just established; prin urmare ("consequently, therefore") is the formal conclusion-drawer of argumentation. All three are (formal) and belong to reports, news, essays, and speeches — not chitchat. (See sentence connectors for their punctuation and position, and the deci / așadar page for the close relatives.)
Cererea a depășit estimările; ca urmare, stocurile s-au epuizat în două zile.
Demand exceeded estimates; as a result, stocks ran out in two days. (formal)
Bugetul a fost redus. Drept urmare, proiectul se amână până în toamnă.
The budget was cut. As a result, the project is postponed until autumn. (formal)
Toate dovezile coincid; prin urmare, concluzia se impune de la sine.
All the evidence aligns; consequently, the conclusion is self-evident. (formal)
| Marker | Meaning | Direction | Register |
|---|---|---|---|
| de aceea | that's why | cause → result (forward) | neutral |
| de asta | that's why | cause → result (forward) | informal |
| din cauza asta | because of that | cause → result (forward) | neutral, often negative |
| așa că | and so | cause → result (forward) | neutral / spoken |
| ca urmare / drept urmare | as a result | cause → result (forward) | formal |
| prin urmare | consequently | cause → result (forward) | formal |
| pentru că | because | result → cause (backward) | neutral |
The big one: de aceea vs pentru că
Here is the mix-up that catches nearly every English speaker. Both de aceea and pentru că mark the same causal relationship, but they face opposite ways:
- de aceea ("that's why") — you have already stated the cause, and de aceea introduces the result. It points forward.
- pentru că ("because") — you have already stated the result, and pentru că introduces the reason. It points backward.
The same two facts ("it's raining" + "I'm staying home") can be packaged either way:
Plouă, de aceea rămân acasă.
It's raining, that's why I'm staying home. (cause stated, de aceea → result)
Rămân acasă pentru că plouă.
I'm staying home because it's raining. (result stated, pentru că → cause)
Notice they are mirror images. You cannot swap the markers without scrambling the logic: Plouă, pentru că rămân acasă would absurdly mean "It's raining because I'm staying home." The marker must match which half you've already said.
Common Mistakes
Using de aceea ("so/therefore") where the sentence needs pentru că ("because") — pointing the wrong way:
❌ Rămân acasă de aceea plouă.
Direction error — you stated the result (staying home), so the cause needs pentru că. De aceea would point forward to a result that isn't there.
✅ Rămân acasă pentru că plouă.
I'm staying home because it's raining.
The mirror error — pentru că where the result follows the cause and de aceea is wanted:
❌ Plouă pentru că rămân acasă.
This literally claims the rain is caused by your staying home. You stated the cause first, so the result needs de aceea.
✅ Plouă, de aceea rămân acasă.
It's raining, that's why I'm staying home.
Pairing a formal result marker with casual content, producing a register clash:
❌ Eram super obosit, prin urmare m-am dus la culcare.
Clash — prin urmare is formal/written; with casual content use the spoken așa că.
✅ Eram super obosit, așa că m-am dus la culcare.
I was super tired, so I went to bed.
Stacking two consequence markers, doubling the same job:
❌ Era închis, așa că de aceea ne-am întors.
Redundant — așa că and de aceea both introduce the result. Use one.
✅ Era închis, așa că ne-am întors.
It was closed, so we went back.
Key Takeaways
- The result-pointing markers — de aceea / de asta (that's why), din cauza asta (because of that), așa că (and so), ca urmare / drept urmare / prin urmare (consequently) — all state the cause first and point forward to the consequence.
- pentru că ("because") does the opposite: it states the result first and points backward to the cause.
- Choosing between de aceea and pentru că is purely about which half you've already said — get the direction right and the rest follows.
- Register ladder for "so / as a result": de asta (informal) → de aceea / așa că (neutral / spoken) → ca urmare / drept urmare / prin urmare (formal).
- din cauza asta leans negative (cause of a problem); for a positive cause prefer datorită ("thanks to").

- Discourse Markers: OverviewB1 — A survey of the words that organize talk rather than carry meaning — additive (în plus, de asemenea), contrastive (totuși, însă, pe de altă parte), causal/consecutive (deci, prin urmare, așadar), reformulative (adică, cu alte cuvinte), exemplifying (de exemplu, bunăoară), and interactional fillers (păi, mă rog, gen). The casual fillers vs the formal connectors are a sharp register signal.
- Consecutive Markers (deci, așadar, prin urmare)B1 — How Romanian signals 'so / therefore' in real talk — neutral deci, formal așadar and prin urmare, plus ca atare and în consecință — and the double life of deci as a logical 'therefore' AND a pervasive spoken filler ('so…', 'I mean'). The deci-vs-așadar split is one of the loudest register tells in the language.
- Sentence Connectors (deci, totuși, prin urmare, așadar)B1 — The connectors that link whole sentences rather than join clauses — deci (so/therefore), prin urmare and așadar (consequently, formal), totuși (however), de aceea (that's why), în plus (moreover), de altfel (besides) and pe de altă parte (on the other hand) — with their clause-initial position, comma punctuation, and the register signal that separates casual deci from formal așadar.
- Causal Conjunctions (pentru că, fiindcă, deoarece, căci)A2 — The Romanian 'because' family — pentru că (neutral), fiindcă (colloquial), deoarece (formal/written), căci (literary), din cauză că / datorită faptului că — all taking the indicative, graded by register, plus the dangerous near-homonym pentru ca…să (so that).
- Spoken vs Written RomanianB2 — Medium (spoken vs written) and formality (informal vs formal) are two independent axes. Spoken Romanian favors the o-să future, ăsta/asta, dropped final -l, clitic fusion, fillers, repair, and dislocation (Cartea, am citit-o); written Romanian favors the voi-future, acesta, full forms, dense subordination, and — in narrative — the perfectul simplu. Crucially, even a formal SPEECH keeps some spoken features that a formal LETTER would not, so 'spoken vs written' is not the same cut as 'informal vs formal'.
- Organizing Discourse and Turn-TakingB2 — The etiquette of managing a Romanian conversation: opening and closing exchanges gracefully, holding the floor (păi, deci, stai să-ți zic), interrupting politely (Scuze că te întrerup, Doar o secundă), changing topic without whiplash (Apropo de asta, În altă ordine de idei), and structuring a narration (Întâi…, Apoi…, La final). The discourse-marker pages supply these as forms; here the focus is the social choreography of taking and yielding the floor.
