The labials are those consonants which are articulated chiefly by the lips; among which, Dr. Webster reckons b, f, m, p, and v.

"The labials are p, b, f, v; the dentals t, d, s, z; the palatals g soft and j; the gutturals k, q, and c and g hard; the nasals m and n; and the linguals l and r."Ib., p. 25.
