ag- prefix
assimilated form of L. ad- to, at, before g, as in ag-glūtinātus, ag-gravātus, ag-gressio. Reduced in OFr. to a-, and so entered Eng. as in a-greger, a-grever, a-grege, a-grieve. Afterwards refashioned after L. in all words that survived into mod.Eng., exc. a-gree (ag-grātāre), and spelt ag- in all words taken from L. into mod.Fr. or Eng. As in other forms of ad-, erroneously substituted in 16th c. for a- from other sources, as a(g)grise, OE. a-grísan.
In certain words, before g sounded |dʒ|, the original ad- has been preferred, as ad-geniculate, ad-generate; before gn- a- is found, as a-gnate (also ad-nate), a-gnize, a-gnomen (also ad-nomen). |
