Word Origin and History for semi-moist

moist

adj.

late 14c., "moist, wet; well-irrigated," from Old French moiste "damp, wet, soaked" (13c., Modern French moite), from Vulgar Latin *muscidus "moldy," also "wet," from Latin mucidus "slimy, moldy, musty," from mucus "slime" (see mucus). Alternative etymology [Diez] is from Latin musteus "fresh, green, new," literally "like new wine," from musteum "new wine" (see must (n.1)). If this wasn't the source, it influenced the form of the other word in Old French. Related: Moistly; moistness.
