Jerome

To be a little bit more precise: the second element of Hieronymos is actually ὄνυμα (onyma), which is the Aeolic and Doric Greek form of the Attic Greek word ὄνομα (onoma) meaning "name". If the name had actually contained the Attic Greek word, it would have been written as Ἱερώνομος (Hieronomos). [noted -ed]

It might be sensible to specify this in the description, even if only in order to avoid confusion with names where Attic Greek ὄνομα (onoma) is actually in the name, such as Ὀνομακλῆς (Onomakles; Onomacles in Latin) and Ὀνομάκριτος (Onomakritos; Onomacritus in Latin).

Oh, and check out the conjugation table for ὄνομα (onoma), in case you might be wondering if the -y- instead of -o- in Hieronymos could have been due to conjugation:

I've read JEROME is a variant spelling of GEROME from the Greek, meaning OF HOLY PERSON or SACRED NAME.
