dam: [12] Dam, appropriately enough for a word related to the human control of water-courses, seems to have been borrowed from Middle Dutch dam. It appears to have been a fairly widespread West and East Germanic word, subsequently borrowed into North Germanic, but its ultimate source is not known.
dam (n.1)
"water barrier," early 14c., probably from Old Norse dammr or Middle Dutch dam, both from Proto-Germanic *dammaz (cognates: Old Frisian damm, German Damm), which is of unknown origin.
dam (n.2)
"animal mother," c. 1300, variant of dame (q.v.), also originally used, like that word, for "lady, mother;" but meanings diverged into separate spellings by 16c.
dam (v.)
late 15c., from dam (n.1). Related: Dammed; damming.
