Wikipedia:Coinage may be cited directly

By the nature of wikipedia, articles are centered around a word, every word first appeared in text somewhere, that first use may be cited directly. It is not necessary to cite a secondary source that speaks about first usage, just cite the first usage, for example:

Write:

" The phrase "RNA World" was first used by Nobel laureate Walter Gilbert in 1986, in a commentary on how recent observations of the catalytic properties of various forms of RNA fit with this hypothesis. "

And not

" According to an ephemerides article by a digital newspaper, the phrase RNA world was first used by Nobel Laureate Water Gilbert in 1986. "

Cut the middleman.

If an earlier usage of the word arises, it will be replaced, and so the Wikipedia project will naturally find the origin of a word.
