thousand
number[C/U] Both
pl: thousands
This word functions as a bridge between precise counting and vague estimation. When used with a specific number, it is a rigid mathematical value. However, when used without a determiner, it often shifts into a hyperbolic expression of a very large, though not necessarily exact, amount. In social contexts, it carries a psychological weight of abundance. Saying something happened a thousand times suggests exhaustion or obsession rather than a literal tally. It is less formal than ten hundred and more common in conversational English to denote scale.
Countable when referring to the specific number as a unit (two thousand). Uncountable when used as a collective mass to describe an immense quantity (thousands of people).
