widespread
Widespread means found across a wide area or among many people, not confined to one spot. It joins wide and spread, and that is its whole picture: something that has reached far and is now common over a region or a population. A rumour, a disease, a belief, or a practice can be widespread. The word stresses extent rather than depth — widespread support may still be shallow — and it tends to appear just where a problem has stopped being local and turned general.
- widespread support
- widespread damage
- become widespread
- widespread concern
- widespread adoption
A strong upgrade from 'common' or 'everywhere' in TOEFL/IELTS Writing about social trends, health, and technology ('widespread use of smartphones'). It modifies extent, not intensity — pair it with nouns like support, concern, damage, adoption. Note it is one word and usually attributive ('a widespread belief'). The antonyms localized and isolated are handy for contrast paragraphs.
