Masculine Past Tense

In Ukrainian, the past tense functions differently than the present. While the present tense changes based on who is speaking (I, you, he), the past tense only cares about the gender and number of the subject. The masculine past tense is unique because it uses the suffix -в (or a zero ending), whereas all other past tense forms (feminine, neuter, and plural) use the suffix -л-.

1. Standard Formation:
For most verbs, remove the -ти ending and add -в. This includes the most common verb, бути (to be):

• бу-ти → був (he / I [masc.] / you [masc.] was/were)
• працюва-ти → працював (he / I [masc.] / you [masc.] worked)
• бачи-ти → бачив (he / I [masc.] / you [masc.] saw)

2. Consonant Stems (Zero Ending):
If the stem ends in a consonant after removing -ти, the masculine form usually takes no suffix (a 'zero ending'). Often, the vowel о or е in the root changes to і in this closed syllable (with rare exceptions like я changing to і in лягти):

• нес-ти → ніс (he carried)
• мог-ти → міг (he could)
• ляг-ти → ліг (he lay down)

Verbs ending in -рти also follow this zero-ending rule:

• вмер-ти → вмер (he died)
• тер-ти → тер (he rubbed)

3. Verbs ending in -сти/-зти:
Many verbs ending in -сти or -зти take a zero ending (e.g., нести → ніс, везти → віз). However, if their underlying root ends in a dental stop (д or т), this consonant drops out and they take the -в suffix. Note that for verbs like вести, the vowel alternation е → і applies here because the syllable becomes closed (вед-в → вев → вів):

• вес-ти (root вед-) → вів (he led)
• крас-ти (root крад-) → крав (he stole)
• їс-ти (root їд-) → їв (he ate)

An important exception is рости (to grow), which drops the т but takes a zero ending and vowel alternation: ріс (he grew).

4. Verbs with -нути:
For verbs denoting a gradual process, the suffix -ну- is often dropped, resulting in a zero ending, though parallel forms exist:

• сохнути → сох / сохнув (he dried)
• замерзнути → замерз / замерзнув (he froze)

However, for sudden, single actions, the -ну- is always kept and takes -в:

• стрибнути → стрибнув (he jumped)

5. Reflexive Verbs:
For verbs with the reflexive suffix, the suffix -ся is added after the masculine -в. If the masculine form has a zero ending, -ся is added directly to the final consonant:

• митися → мився (he washed himself)
• дивитися → дивився (he watched)
• берегтися → берігся (he protected himself)

6. Irregular: іти (to go):
The verb іти is highly irregular in the past tense. The masculine form is ішов (or йшов). Prefixed forms follow the same pattern (e.g., знайти → знайшов, піти → пішов).

Note on Pronunciation: The final -в is pronounced like a soft English 'w' (as in 'now' or 'cow'), not like a 'v' or 'f'.
