-or

2. (electrical science) Appended to the names of members of classes of components, especially those that have an extensive property name of the same root suffixed with -ance

English generally appends this suffix where Latin would do it—to the root of a Latin-type perfect passive participle. For other words, English tends to use the suffix -er. Occasionally both are used (protester vs. protestor).

• (Classical) IPA^(key): /or/, [ɔr]

For earlier -ōs, from Proto-Indo-European *-ōs, for original *-oss, i.e. the neuter s-stem *-os with masculine nominative *-s. The ō from the nominative case was made common to all cases originally with non-ablauting o (the three exceptions were arbor, mulier and Cerēs). Afterwards nom.sg. -ōr > -or, by Latin sound laws. Thus paradoxically, as in the r-stems (soror, -tor), in the resulting paradigm the one form with a short stem vowel is the only form whose stem was etymologically long.[1]
