Learner Path: B1 Intermediate

B1 is where you stop assembling sentences from memorised pieces and start generating them from rules. The level is built on a handful of productive systems: aspect derivation (turning any verb into its partner with a prefix or suffix), prefixed verbs of motion (combining a direction with a manner), the conditional and щоб (talking about the unreal and the intended), the many meanings of reflexive -ся, graded modality, and relative clauses. Each system is generative — learn the rule once and you can produce hundreds of forms. This path orders them so each builds on the last: aspect formation underlies prefixed motion; the conditional underlies якби and conditional sentences.

This path assumes the A2 Core Grammar path is complete — full case system, past and future, and aspect as a concept.

Stage 1 — Genitive plural and counting that finally works

• Genitive Plural: Forms — the trickiest plural endings (often a zero ending: книг, жіно́к); the gateway to numerals.
• Genitive After Numbers and Quantity — why п’ять книг but дві кни́ги; counting demands the genitive plural from "five" up.
• Numeral–Noun Agreement (The Hard Part) — the full 1 / 2-3-4 / 5+ system that decides the noun's case and number.

Stage 2 — Aspect as a productive system

At A2 you memorised aspect pairs. At B1 you learn to derive them — and this skill is the prerequisite for prefixed motion in Stage 3.

• Forming Aspect Pairs: Prefixes — how a prefix perfectivises: писа́ти → написа́ти. Do this before prefixed motion.
• Forming Aspect Pairs: Suffixes and Stems — the reverse direction: a suffix re-imperfectivises a prefixed verb (записа́ти → запи́сувати).
• When Prefixes Change Meaning (Aktionsart) — the catch: some prefixes add meaning, not just aspect (писа́ти → переписа́ти, "rewrite").
• Imperfective vs Perfective: The Master Decision — the decision flowchart that ties the whole system together.

Stage 3 — Prefixed verbs of motion

Now combine Stage 2's prefixes with A2's motion verbs. A prefix on a motion verb gives direction (при- = arrival, ви- = exit) — and simultaneously perfectivises it.

• Prefixed Verbs of Motion: Overview — how при-/ви-/під-/від-/пере- attach a direction to іти and їхати.
• Піти, Поїхати and the Inceptive По- — the special по- that means "set off," the most common prefixed motion verb of all.
• Choosing the Right Motion Verb: Summary — the full decision tree for any "go/come" situation.

Stage 4 — The conditional, then its dependents

Learn to form the conditional first; everything in this stage and the next depends on it.

• The Conditional: би / б — past-tense form + the particle би/б; learn the formation before any use.
• Using the Conditional (Якби, Polite Requests, Wishes) — hypotheticals, soft requests (я хоті́в би), and wishes.
• Щоб Clauses (Purpose and Subordinate Will) — щоб = "so that / in order to," and it borrows the conditional's -б, so it comes after it.
• Якщо vs Якби ('if') — real conditions (якщо
  • future) vs unreal ones (якби
    • conditional); needs the conditional already in hand.
• Conditional Sentences (Real and Unreal) — assembling the full "if … then …" sentence in both modes.

Stage 5 — The imperative, with aspect

• The Imperative: Formation — you met this at A1; now formalise its endings.
• Aspect in the Imperative — perfective for one specific request (Зачини́ две́рі!), imperfective for general or negative commands (Не зачиня́й!). A real native-vs-foreigner divider.

Stage 6 — The reflexive -ся, in full

• The Many Meanings of -ся — true reflexive, reciprocal, passive, and lexical -ся; one suffix, several jobs.
• When a Verb Needs -ся (and When It Changes Meaning) — вчи́ти ("teach") vs вчи́тися ("study"): the -ся can flip the meaning entirely.

Stage 7 — Modality: can, must, want, should

• Can: Могти vs Вміти/Уміти — possibility (могти́) vs acquired skill (вмі́ти); English "can" hides this split.
• Must / Should: Треба, Мусити, Повинен, Слід — graded obligation, from impersonal тре́ба to strong му́сити.
• Want / Wish: Хотіти, Хотітися, Бажати — desire, including the impersonal мені́ хо́четься ("I feel like").
• Predicative Adverbs (Можна, Треба, Холодно) — the мо́жна / тре́ба / тре́ба було́ impersonal frame with a dative subject.

Stage 8 — Building complex sentences

• Relative Clauses (Який, Що, Хто) — який agrees in gender/number with its antecedent but takes its case from its own clause; the heart of complex description.
• Relative Pronouns (Який, Що, Хто) — the forms and the який / що choice in detail.
• Reported (Indirect) Speech — Ukrainian keeps the original tense (no English-style backshift), which is a relief.
• Indirect Questions — embedding a question with чи ("whether") and the wh-words.
• Double and Multiple Negation — ніхто́ нічо́го не зна́є: Ukrainian requires the negatives to agree, the opposite of formal English.
• Comparative and Superlative Adverbs — "faster, the most carefully," to refine how you describe actions.

Milestones

You are ready for B2 when you can:

• Derive a verb's aspectual partner yourself, choosing the right perfectivising prefix or imperfectivising suffix.
• Attach the right directional prefix to a motion verb (приї́хати, ви́йти, перейти́) and get the aspect for free.
• Build an unreal conditional (якби … я б …) and a purpose clause with щоб without hesitation.
• Pick imperfective vs perfective imperatives correctly, including under negation.
• Use -ся knowingly — and notice when it changes the verb's meaning.
• String clauses together with який, report speech, and let your negatives agree.

With these systems automatic, you are ready for B2, where you consolidate participial style, the passive, and the finer points of word order and information structure.
