About とは限らない

とは(かぎ)らない is regularly used to convey the meaning of '(A) is not necessarily so', or 'there is no guarantee that (A)'. This expression utilizes the case marking particle と in its use for highlighting results, the adverbial particle は, and the negated form of the う - Verb (かぎ)る 'to limit'.
This structure may be used with verbs, い-Adjectives, な-Adjectives, or nouns. However, will be required after な-Adjectives and nouns.
