- S
- S S ([e^]s),
the nineteenth letter of the English alphabet, is a
consonant, and is often called a sibilant, in allusion to its
hissing sound. It has two principal sounds; one a mere
hissing, as in sack, this; the other a vocal hissing (the
same as that of z), as in is, wise. Besides these it
sometimes has the sounds of sh and zh, as in sure, measure.
It generally has its hissing sound at the beginning of words,
but in the middle and at the end of words its sound is
determined by usage. In a few words it is silent, as in isle,
d['e]bris. With the letter h it forms the digraph sh. See
Guide to pronunciation, [sect][sect] 255-261.

Note: Both the form and the name of the letter S are derived from the Latin, which got the letter through the Greek from the Ph[ae]nician. The ultimate origin is Egyptian. S is etymologically most nearly related to c, z, t, and r; as, in ice, OE. is; E. hence, OE. hennes; E. rase, raze; erase, razor; that, G. das; E. reason, F. raison, L. ratio; E. was, were; chair, chaise (see C, Z, T, and R.).
