Grammar Rule in 30 Seconds

Most Bulgarian verbs follow a pattern in the Imperfect, but 'съм' (to be) and 'мога' (can) are the essential exceptions you must memorize.

  • The verb 'съм' (to be) uses the stem 'бя-' in the imperfect: 'бях', 'беше', 'беше'.
  • The verb 'мога' (can) uses the stem 'може-' in the imperfect: 'можех', 'можеше', 'можеше'.
  • Irregular verbs often retain their stem vowel changes throughout all persons in the imperfect tense.
Subject + Irregular Stem + Imperfect Ending (-х, -ше, -ше, -хме, -хте, -ха)

Meanings
