Anatomy The soft palate.
Zoology A ciliated swimming organ that develops in certain larval phases of many marine gastropod mollusks.
A thin membrane layer, resembling a veil, such as for example:
An accessory cloud resembling a veil expanding over a big distance. Ordinarily associated with cumulus and cumulonimbus.
A curtain or covering; -- placed on different membranous partitions, especially into soft palate. See under Palate.
