When you can't use it
- The 'approximately' sense (一週間ばかり) sounds slightly formal or dated. In everyday speech ぐらい・くらい is the natural choice for rough amounts (三日ぐらい). approximately
Easily confused with
〜だけ だけ states a precise limit and is neutral (三人だけ = 'exactly three'). ばかり means 'nothing but ~' and colours the situation as excessive or one-sided (お菓子ばかり = 'sweets and nothing else'). しか しか takes a negative and means 'only, and that's not enough' (水しかない). ばかり takes a positive predicate and emphasises that one thing dominates everything else. 〜たばかり Attached to the た-form, ばかり instead means 'just (now) did ~' (着いたばかり = 'just arrived') — a time sense, not the 'only/nothing but' sense here.
