Meaning & usage
a sharpened point
Where this word comes from
By surface analysis, acuō (“make sharp or pointed, sharpen”) + -men (noun-forming suffix), from acus (“a needle, a pin”). The linguist Douglas Q. Adams suggests that the form is comparable to Tocharian B akwam, which Adams argues could be a descendant of Proto-Indo-European *h₂eḱ-u-mn-. However, the Latin form—if inherited directly from Proto-Indo-European—would more likely derive from a term of the shape *h₂eḱu-h₂-m-n-.
