Etymology

[edit]

From pinna (plume, wing; parapet). Pinnāculum appears in the Vulgate as a calque of Ancient Greek πτερύγιον (pterúgion, pinnacle), diminutive of πτέρυξ (ptérux, wing) (alternative translations of the Greek include fastīgium and pinna itself).[1] Therefore, the end of the word appears to be the neuter form of the Latin diminutive suffix -culus. However, pinnāculum is not a regularly formed diminutive: there is an irregular change of gender from the feminine base and an unexpected -ā- between the base and the suffix. The form may have been influenced by that of nouns ending in -āculum that were derived from the instrument noun suffix -culum: the Oxford English Dictionary suggests that the form pinnāculum was possibly based on analogy with prōpugnāculum (bulwark, rampart), from prōpugnō +‎ -culum.[2]
