Other definitions for -or (6 of 8)
a suffix occurring in loanwords from Latin, directly or through Anglo-French, usually denoting a condition or property of things or persons (ardor; honor; horror; liquor; pallor; squalor; torpor; tremor), sometimes corresponding to qualitative adjectives ending in -id4 (horrid; pallid; squalid; torpid). A few other words that originally ended in different suffixes have been assimilated to this group (behavior; demeanor; glamour).
The suffix -or2 is now spelled -or in all forms of English, with the exception of the word savior, often spelled saviour in the U.S. as well as in Britain, especially with reference to Jesus.
Other definitions for -or (7 of 8)
a suffix forming animate or inanimate agent nouns, occurring originally in loanwords from Anglo-French (debtor; lessor; tailor; traitor); it now functions in English as an orthographic variant of -er1, usually joined to bases of Latin origin, in imitation of borrowed Latin words containing the suffix -tor (and its alternant -sor). The association with Latinate vocabulary may impart a learned look to the resultant formations, which often denote machines or other less tangible entities which behave in an agentlike way: descriptor; plexor; projector; repressor; sensor; tractor.
