Helps to Latin Translation at Sight

by Edmund Luce

[(1)] A few simple rules for the vowel changes of verbs in composition. Thus:

a before two consonants (except ng) often changes to e.

E.g. sacr-o, con-secr-o; damn-o, con-demn-o.

a before one consonant and before ng often changes to i.

E.g. fac-io, ef-fic-io; căd-o, ac-cid-o; tang-o, con-ting-o.

But grăd-ior, ag-grĕd-ior.

a before l and another consonant changes to u.

E.g. salt-are, in-sult-are.

ĕ changes to ĭ (but not e before two consonants) and ae to i.

E.g. ten-ere, ob-tin-ere; quaer-ere, in-quir-ere.
