Common mistakesConfused with 'require' — 'demand' is stronger than 'require'., Using 'demand' without an object — it needs something to demand., Mixing it up with 'request' — 'request' is more polite.'Need' is sometimes incorrectly followed by a gerund (e.g., 'I need going')., Confusing 'need' with 'want'; 'need' indicates necessity., Mistaking the past tense 'needed' for 'needing' incorrectly in sentences.
Usage notesUse 'demand' when you want something with urgency or authority. It's neutral but can be seen as aggressive in casual situations. Avoid using it when making polite requests.Use 'need' in everyday situations when expressing requirements. Avoid using it in very formal contexts; in such cases, 'require' may be more appropriate.
