Grammar note (regular): Regular verbs and adjectives conjugate predictably. Before 어-series suffixes, vowels may contract (가 + 아 → 가, 보 + 아 → 봐), but no consonant in the stem changes. If the final vowel of the stem is ㅏ or ㅗ, use 아; otherwise use 어. Consonant-final stems: 먹 + 어 → 먹어; vowel-final: 가 + 아 → 가.
