Word Origin & History

early 14c., from O.Fr. deien, from L.L. decanus "head of a group of 10 monks in a monastery," from earlier secular meaning "commander of 10 soldiers" (which was extended to civil administrators in the late empire), from Gk. dekanos, from deka "ten." Replaced O.E. teoðingealdor. College sense is from
1570s (in L. from 1271).

O.E. dysig "foolish, stupid," from P.Gmc. *dusijaz. Meaning "having a whirling sensation" is from mid-14c.; that of "giddy" is from c.1500 and seems to merge the two earlier meanings. Used of the "foolish virgins" in early translations of Matthew xxv; used especially of blondes since 1870s.
