Dictionary-Form VERB必要がある as “need to, have to VERB”

Dictionary-Form VERB必要がある as “need to, have to VERB”

This grammar pattern uses the noun-word 必要(ひつよう), which means “necessity, need,” and the がある (“there is ___, have ___”) grammar construction with the Dictionary-Form of a VERB to mean “there is a need to do VERB,” or, more naturally, “need to VERB, have to VERB.” When this grammar pattern is used in the Negative Form, the particle は is commonly used in lieu of the particle が.
