   ‎survive + ‎-or → ‎survivor

   Synonyms: -er, (casual) -ster

使用する際の注意点

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

語源 1

From Proto-Italic *-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 かつ 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]
