They probably haven’t practiced in Korean 🇰🇷

Sentence info.

Breakdown of "아마도연습하지않았을거야" (amado yeonseuphaji anasseul geoya):

1. Structure:
 • 아마도 (amado) means “probably.”
 • 연습하다 (yeonseuphada) means “to practice.” When forming the negative, the verb stem is used with the construction –지 않다.
 • 연습하지 않다 becomes “do not practice.”
 • The form wasn’t simply “안 한다” but “하지 않다” is used here, then made past with –았, giving 연습하지 않았을.
 • 거야 (geoya) is a contraction of “것이다” which, attached to a clause, expresses supposition or prediction (“it must be that…”).

2. Tips for Remembering:
 • Note that adverbs like 아마도 come first, setting the tone for probability.
 • For negative verbs, remember to attach –지 않다 (or its contracted forms) to the verb stem.
 • The ending 거야 signals that you are stating an assumption, similar to “probably” in English.
 • Practicing the transformation of a positive sentence to its negative form (e.g., 연습하다 → 연습하지 않다) will help solidify the pattern.

3. Alternate Ways to Express “They probably haven't practiced”:
 • "아마도 연습 안 했겠지." (amado yeonseup an haetgetji)
 • "그들은 아마 연습을 하지 않았을 거예요." (geudeureun amado yeonseupeul haji anasseul geoyeyo) – note the added subject “그들은” for “they” and a more formal ending.
