- 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
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.
