Letter

X (lower case x)

1. A letter of the Kwak'wala alphabet, written in the Latin script.

Etymology

Borrowed from Ancient Greek Χ (Kh, “chi”), which represented /ks/ in the dialects of most of the Greek mainland and Euboea.

Pronunciation

The sound of X was like that of the Greek Ξ (X, “xi”), that is /ks/, although etymologically it represented not only cs (as in lūx, from luc-s, and dīxī, from dic-si), but also gs (as in lēx, from leg-s; rēxī, from reg-si); hs (as in trāxī, from trah-si; vexī, from veh-si); and chs (as in the word onyx, from onych-s, borrowed from the Greek). The hardening of a softer final (g, h, ch) before s into the с sound, which occurs in the last-mentioned cases, is found also in several roots ending in v and u: nix for niv-s, vīxī for viv-si, connixī for conniv-si, fluxī for fluv-si, from fluō (root fluv-; compare fluvius), struxī for stru-si.

Less frequently x has arisen from the combinations ps and ts: proximus for prop-simus (from prope), nīxus for nit-sus (from nītor), the latter being used along with the collateral form nīsus, as also connīvī with connixī, and mistus (from misceō) with mixtus.

An exchange of the sounds ss or s and x, took place in axis for assis and laxus for lassus. In the later language of the vulgar, the guttural sound in x disappeared, and s or ss was often written for it; as vis for vix, visit for vīxit, unsit for unxit, conflississet for conflixisset, in late inscriptions; hence regularly in Italian, and frequently in the other Romance tongues, the Latin x is represented by s or ss.

By a mere graphic variation, one of the constituent sounds of x is often expressed in inscriptions (but not the earliest) by an additional с or s; as SACXO or SAXSO for saxō; VCXOR or VXSOR for uxor; CONIVNCX or CONIVNXS for conjunx; even both sounds are sometimes thus expressed, VICXSIT for vīxit.
