pinnaculum

Etymology
From. appears in the Vulgate as a, diminutive of (alternative translations of the Greek include  and  itself). Therefore, the end of the word appears to be the neuter form of the Latin diminutive suffix. However, is not a regularly formed diminutive: there is an irregular change of gender from the feminine base and an unexpected  between the base and the suffix. The form may have been influenced by that of nouns ending in that were derived from the instrument noun suffix : the Oxford English Dictionary suggests that the form  was possibly based on analogy with, from.
