V-ている / Adj / N-の + 間while; during
Used to describe an action or state that continues for the entire duration of another state. Both the main clause and the 'aida' clause must span the same time period. Formation involves the dictionary or progressive form for verbs, and the 'no' particle for nouns.
Common mistakes
- Confusing with 'aida ni' which describes a momentary action.
- Using the past tense in the 'aida' clause when describing a continuous state.
- Forgetting the 'no' particle with nouns.
