Etymology
the word 'grimace' entered english in the mid-17th century from the french word of the same spelling, which meant 'grotesque or comic expression'. the french term likely derived from the spanish 'grimazo', meaning 'caricature' or 'grotesque face', which itself is an alteration of 'grima', meaning 'fright' or 'ghost'. this spanish root can be traced further back to a germanic source, related to the old english 'grima', meaning 'mask' or 'helmet', and is cognate with the modern english word 'grim'. the etymological journey thus connects the concept of a distorted facial expression to older ideas of masks, specters, and a frightening appearance.
Analysis
the entire word 'grimace' is treated as a single, unsegmentable unit in modern english.
