Also 6 caskytt, 7 cascate, 9 casquet. [Of uncertain etymology: the form suggests a dim. of CASK; but casket in fact occurs earlier than cask, and is without precedent as to meaning in Fr. or other lang.
F. casquet is quoted by Littré only of 16th c. in sense light helmet, which is also the sense of Sp. casquete. Skeat conjectures that casket may have been corrupted from Fr. cassette small casket, chest, cabinet, etc., dim. of casse box, chest, CASE; this would give the sense, but evidence of, or analogy for, the corruption is wanting. Moreover Littré has F. cassette only from 16th c., when it may have been adopted from It. cassetta: there is no trace of it in Eng. in 15th or 16th c.]
