About ひつようがある

Like 必要(ひつよう), 必要(ひつよう)がある is an expression which is used to highlight the 'need' or 'necessity' of something. The primary difference being that 必要(ひつよう)がある highlights the need to 'do (A)', and will therefore be used with verbs (without the need for nominalization).

To use 必要(ひつよう)がある, just attach it after the plain form of the verb that you want to highlight the 'need' for.

As we can see, this construction is simply the combination of a verb + 必要(ひつよう) (creating a verb modified noun), the case marking particle , and the う-Verb ある. In this way, it just means 'the need of doing (A) exists'.

Naturally, this grammar pattern may also be used negatively, to highlight that there is 'no need to do (A)', or that 'doing (A) is not necessary'.
