  • capable of producing something, especially in abundance; fertile
  • yielding good or useful results; constructive
  • of, or relating to the creation of goods or services
  • (linguistics, of an affix or word construction rule) consistently applicable to any of an open set of words

  • Moreover, this relationship is a productive one, in the sense that when new Adjectives are created (e.g. ginormous'' concocted out of ''gigantic'' and ''enormous''), then the corresponding Adverb form (in this case ''ginormously'') can also be used. And in those exceptional cases where Adverbs do not end in ''-ly'', they generally have the same form as the corresponding Adjective, as with ''hard'', ''fast , etc.
  • (medicine) of a cough, producing mucus or sputum from the respiratory tract
  • (medicine) of inflammation, producing new tissue
  • Usage notes

    In English, the plural suffix “-es” is productive' because it can be appended to an open set of words (singular nouns ending in sibilants). Thus, if a new word with that pattern becomes an English noun (e.g. *''examplex''), it would have a default plural (e.g. *''examplexes'') because “-es” is ' productive .
