に限（かぎ）らず is a sentence pattern in Japanese used that highlights when something is ‘not just (A), but (B) too’, or ‘not only (A), but also (B)’. It is a combination of に, the う-Verb 限（かぎ）る ‘to limit’, and the literary auxiliary verb ず, which connects with verbs in the same way, and carries the same meaning as ない.
This structure will appear after nouns, before the (B) part of the sentence will go on to explain things that can be included in the same scope or category as (A).

Occasionally, も may be added for extra emphasis in the (B) part of に限らず sentences. This is especially true when several extra things are being indicated, not just (B). For example, ‘(B) も (C) も’.
