用法筆記

Necessarily is most common in negative statements with 'not'. In affirmative statements, it carries a formal or academic tone. Learners should avoid using 'necessarily' alone in a simple affirmative sentence where 'certainly' or 'definitely' would be more natural — for instance, say 'She will certainly arrive on time' rather than 'She will necessarily arrive on time.' The negative pattern (not necessarily) is the structure you will hear in everyday conversation.
