This evolutionary trajectory assumes the simplicity to complexity route of biogenesis, a point of view that is not universally accepted.}}

*1847 , John Johnson, The theological works of the rev. John Johnson :

Adjective

(en adjective)

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.
