使い分け解説:
- 全然: Always used with a negative verb or phrase (e.g., 全然ない, 全然分からない). In informal speech, it's sometimes used positively, but this is non-standard.
- 必ずしも: Indicates that a certain rule, generalization, or expectation is not necessarily or always true. Used with negative verbs. Often used as 必ずしも〜とは限らない or 必ずしも一致しない. ⚠️ Haruka's Voice Column: 'Not always/not necessarily! "Love manual steps aren't necessarily the correct answer. Our unique sweet newlyweds route is the best optimal solution, Haruka-san!" ...っ! Not necessarily manual! B-Baka!
