The existence in Spanish of the singular form párpado
(palpetrum), a survival of Latin palpebrae (palpetrae), is a
paradigmatic example of a series of common linguistic phenomena which
gerzerally are well described in the study of the evolution of Latin into the
romance languages. Among these phenomena the following can be cited:
changes in grammatical gender of words referring to parts of the body,
double stressing of words whose penultimate syllabe occurs before «muta
cum liquida», alternation and switching positions of dfferent suffixes, and
the influence of Greek words on Latin versions of Greek technical books.
