Ukrainian verbs have three moods: indicative (ді́йсний), conditional (умо́вний) and imperative (наказо́вий).

1. Indicative mood expresses factual statements, opinions or questions;
2. Conditional mood expresses desired actions or hypothetical situations. The conditional mood is formed by the past tense of the verb with the particle “б (би)”, which usually follows the verb;
3. Imperative mood: expresses command, prohibition or advice.
