Origin of the term liquid ..

[Stuart Rosen <stuart@xxxxxxxxxxxxxxxxxxx>]

from John Wells, Phonetics & Linguistics, UCL <wells@xxxxxxxxxxxxxxxxxxx>:

The origin of the term 'liquid' is a Latin (mis)translation of a Greek 
technical term. The Greek grammarians used _hygros_ 'fluid' for r, l, n, m, 
in reference to the fact that when they follow a plosive (as in tr) they 
permit the quantity of the preceding syllable containing a short vowel to 
be "doubtful" (ie it can count as either short or long for metric purposes, 
as in Greek _patros_, Latin _patris_). This term was translated into Latin 
as _liquidus_. In Latin, however, this metric principle does not apply to m 
and n, so the term 'liquid' has come to have a more restricted sense.

See Allen, W.S., 1965, Vox Latina: a guide to the pronunciation of 
Classical Latin, CUP, p. 32.
