Necessary Meaning in English
word
释义
If something is necessary, you need it or it must happen for a particular purpose, result, or situation. It is used for things that are required, not just helpful or nice to have.

Often followed by 'to' or 'for': 'necessary to leave', 'necessary for success'. Stronger than 'helpful' or 'useful', but sometimes less absolute than 'essential'. Common patterns: 'it is necessary to...', 'if necessary', and 'as necessary'. In everyday speech, people also often say 'need' or 'have to' instead.
