    Definition of used in English Dictionary

  • 动词 (Verb)
    1. simple past tense and past participle of use.
      1. (intransitive, as an auxiliary verb, now only in past tense) to perform habitually; to be accustomed.
        1. He used to live here, but moved away last year.

      1. That is or has or have been used.
        1. Economics is a messy discipline: too fluid to be a science, too rigorous to be an art. Perhaps it is fitting that economists’ most-used metric, gross domestic product (GDP), is a tangle too. GDP measures the total value of output in an economic territory. Its apparent simplicity explains why it is scrutinised down to tenths of a percentage point every month.
      2. That has or have previously been owned by someone else.
        1. He bought a used car. ‎
      3. Familiar through use; usual; accustomed.
