masculus

• masclus, mascel (Late Latin, proscribed)

From mās ("male") +‎ -culus (diminutive ending).

• (Classical Latin) IPA^(key): [ˈmas.kʊ.ɫʊs]
• (modern Italianate Ecclesiastical) IPA^(key): [ˈmas.ku.lus]
• Note: the /a/ of this word is presumed to be short as in the oblique stem of the base word, and not long as in the nominative, since word-formation operates on the former.
