英译
The grammar pattern "~ないとも限らない" is used to express that something is not necessarily the case or that it is not always the case.
It is often translated as "not necessarily" or "not always" in English.
This pattern is used to convey the idea that there are exceptions or possibilities beyond what is being stated.
For example, if you say "彼が悪いとも限らない" (Kare ga warui tomo kagiranai), it means "He may not necessarily be bad" or "It's not always the case that he is bad", indicating that there could be exceptions or other possibilities to consider.
