[9] For the explanation of the etymology see Webster"s _Unabridged_.
[10] _For_ is different from _fore_, and corresponds to the German _ver_, different from _vor_.
_A_, _be_, _for_, _ge_, are often indifferently prefixed to verbs, especially to perfect tenses and perfect participles, as well as to verbal nouns.--BOSWORTH.
[11] _Ster_ was the Anglo-Saxon feminine termination. Females once conducted the work of brewing, baking, etc., hence brewster, baxter; these words were afterwards applied to men when they undertook the same work.
_Ster_ is now used in depreciating, as in trickster, youngster.
