Latin

Etymology

From obici? (“to throw or put before or towards”).

Pronunciation

• (Classical) IPA^(key): /?o?.beks/, [?o?b?ks?] or IPA^(key): /?o.beks/, [??b?ks?]
• (Ecclesiastical) IPA^(key): /?o.beks/, [???b?ks]

In Classical Latin, the forms of this word built on the oblique stem obic- may have originally been pronounced with an unwritten /j/ sound, making the first syllable of the word /ob/ (which contains the short vowel /o/ and scans as a heavy syllable because of the coda consonant /b/). For example, in Attic Nights 4.17, Aulus Gellius indicates that the learned grammarian Sulpicius Apollinaris read obicibus with a short o and a doubled ("gemina") letter i where it occurs in Vergil's Georgics with heavy-light-light-heavy scansion; this implies a pronunciation /ob.ji.ki.bus/. The same situation of a single letter I potentially representing a sequence of the consonant /j/ and short vowel /i/ is found with the verb obici? and a number of other prefixed verbs derived from iaci?.

Gellius criticizes as ignorant those who pronounce obici?bat and subices with long vowels (i.e. /o?/ and /u?/) for the sake of the meter, a comment which implies that pronunciations with /ob.ji/ and /sub.ji/ were not universally used for derivatives of iacio during the second century, and may have been simplified in normal speech to /o.bi/ and /su.bi/ for for many speakers of that time.

There is less evidence about the Classical Latin pronunciation of the nominative singular form obex as the word was rarely used in this form.
