- advice
- c.1300, auys "opinion," from O.Fr. avis "opinion," from phrase ce m'est à vis "it seems to me," or from V.L. *mi est visum "in my view," ult. from L. ad- "to" + visum, neut. pp. of videre "to see" (see vision). The unhistoric -d- was introduced in Eng. 15c., on model of L. words in ad-. Substitution of -c- for -s- is 18c., to preserve the breath sound and to distinguish from advise.
