Productivity（non-/un-)

能产性

A general term used in Linguistics to refer to the creative capacity of language users to produce and understand an indefinitely large number of sentences. In this context is seen by some linguists as one of the design features of human language. The term is also used in a more restricted sense with reference to the use made by a language of a specific feature or pattern. A pattern is productive if it is repeatedly used in language to produce further instances of the same type. Non-productive patterns lack any such potential. Semi-productive forms are those where there is a limited or occasional creativity, as when a prefix such as un- is sometimes, but not universally, applied to words to form their opposites.

语言学用这个一般术语指语言使用者产生和理解无穷多句子的创造性能力；特别与动物信递系统的“非能产性”相对立, 被有些语言学家视为人类语言的设计特征之一。这一术语按狭义理解也用来指一种语言对某一特征或型式的利用。一个型式如果在语言中反复使用，即不断出现同一型的不同例，则是能产的。非能产的或者不能产的型式缺乏上述这种潜能。半能产的型式是能产性有限或不常现的型式。
