107. (_a._) In final syllables unaccented original #e# before #s# and
#t# was weakened to #i#: as, #salūtis#, _of safety_, from older
#salūtes# (507).
(_b._) Final #i# became #e#: as, #ante# for #*anti# (Greek ἀντί and
#anti-cipāre#); nominative singular #mare#, from the stem #mari-# (526).
(_c._) In final syllables #o# before consonants changed to #u# except
when preceded by #u# or #v#: as, #fīlius#, _son_, for old Latin #fīlios#
(452); #ferunt#, _they carry_, for older #feront#; #femur#, _thigh_,
nomin. sg. from the stem #femor-# (489); #genus#, _kind_, for #*genos#,
Greek γένος; but #vīvont#, _they live_; #salvom#, _safe_. Not long
before the beginning of our era #o# here also changed to #u# and appears
to have coalesced with the preceding #v# (Quint. 1, 7, 26): as, in
inscriptions: INGENVS (nomin. sg.) for #ingenuos#; SERVM, _slave_
(acc. sg.), for #servom#; NOVM for #novom#, _something new_; so also
#boum#, _oxen_ (gen. pl.), for #bovom# (494). But inasmuch as the
majority of forms in the paradigms of these words retained their #v#, it
was restored in most cases, by analogy, to the forms which had lost it:
as, #servum# for #serum#, because of #servī#, #servō#, etc.; #vīvunt#
for #vīunt#, because of #vīvō#, #vīvis#, #vīvit#, etc.
(_d._) When the stems #fac-# (#facere#, _do_), #cap-# (#capere#, _take_)
appear as second members of compounds, their #a# changes in final
syllables to #e#: as, #artifex#, _artisan_; #auceps#, _bird-catcher_.
After the analogy of these words, compounds with #dīcere# and #īre# have
#e# in the nom. sg.: as, #iūdex#, #iūdicis#, _judge_ (from #iūs# and
#dīcere#); #comes#, _companion_ (from #com#, _with_, and #īre#); see
136, 2.
