Synonym Usage
Need, necessity imply a want, a lack, or a demand, which must be filled. Need, a word of Old English origin, has connotations that make it strong in emotional appeal: the need to be appreciated. Necessity, a word of Latin origin, is more formal and impersonal or objective; though much stronger than need in expressing urgency or imperative demand, it is less effective in appealing to the emotions: Water is a necessity for living things.

Etymology
Origin of need
First recorded before 900; Middle English noun nede, Old English nēd ( West Saxon nīed ), cognate with German Not, Old Norse nauth, Gothic nauths
Explanation
A need is something essential: people need food, water, and shelter. When you lack them, you're in need. Besides physical needs like sleep, people have lots of psychological needs: like for love and friendship. To pass an exam, you need to study. To lose weight, you need to exercise more and eat less. Drug addicts feel a physical need for their drug — so do smokers. Often, we feel we need things that we actually just want: like a new video game or car. When someone is trying hard to get something, they might say "I need it!"
