Notes for -or- representing /ə/
- chorizo
The Macmillan English Dictionary has this transcription, but the audio sample, /ɒr/ (which is both common and acceptable). - collaborator
This is not excluded together with other words ending "-or" because of the /ə/ in the third syllable. - corpora, corporate, corporation, and corporatism
This sound is in the second syllable. See/ also under /ᴐ:/. - correlative
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but a common alternative is /əʊ/ (followed by /r/). - corroborate, corroboration, and corroborative
This sound occurs in both "or" syllables. - elaborate
The -or- syllable represents /ə/ in both the adjective (last syllable /ət/) and the verb (last syllable /eɪt/). - extempore
See con amore note (exceptional "-ore" words [link to /ᴐ:/ section]). - for
When unstressed. See also under /ᴐ:/. - forbad[e]
For both spellings of this irregular past, the Macmillan English Dictionary gives the transcription /æ/ but gives the (same) audio sample with /eɪ/ in the second syllable. This seems to be a mistake - though it is a common one. - forlorn
The Macmillan English Dictionary transcription and audio sample have this vowel (with /ə/ in the first syllable) but many speakers use /ᴐ:/ in both syllables. - forsake, forsaken, and forsook
The Macmillan English Dictionary has this transcription, but the audio sample uses /ᴐ:/ (a common and perfectly acceptable variant). - importune
Note that in the derivative "importunate" (not listed by the Macmillan English Dictionary ) the -or- represents the sound /ᴐ:/. - incorporate
This sound is in the third syllable. See also under /ᴐ:/. - Monsignor
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but a version with /ᴐ:/ is common (especially in a Spanish context - "Monsignor Quixote", for example). - neighbor
This escapes the usual exclusion of words ending "-or" as the agent-making suffix does not work in the usual way. Whereas an actor acts and a director directs, a neighbor does not *neighb. - oration
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but /ɒ/ is common. - sorority
This sound is in the first syllable. See also /ᴐ:/. - uncorroborated
Both instances of -or- represent this sound, although /ə/ is acceptable in the second syllable.
Notes for -or- representing /ɜ:/
- worsted
This is the past simple and past participle of the verb "to worst". The Macmillan English Dictionary does not list the verb "worst" ; nor does the Collins English Dictionary. The Cambridge Advanced Learners' Dictionary lists it, but calls it "old-fashioned". The past simple of this verb is more common, I would guess, than the present, as "worsted in an argument" is a (relatively) common collocation.
Notes for -or- representing /ɒ/
- arboriculture
The Macmillan English Dictionary has this sound in the audio sample, but the transcription has /ə/ (presumably a mistake - I have never heard it in any other context). - chorale
The Macmillan English Dictionary has this transcription, but the audio sample uses /ə/ (which is both common and acceptable). - forehead
This is also sometimes pronounced with /ᴐ:/ - forex
The Macmillan English Dictionary has this transcription, but the audio sample uses /ᴐ:/. - horrendous
The Macmillan English Dictionary has this transcription, but the audio sample uses /ə/. - hydrochloric acid
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but some speakers use /ᴐ:/ (reflecting its relation to "chlorine"). - phantasmagoria
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but some speakers use /ᴐ:/ which the Cambridge Advanced Learners' Dictionary identifies as the American English pronunciation - although it is common also in British English.
Notes for -or- representing /ʌ/
- thoroughbred
This is the sole representative of several other words that use "thorough-" as a prefix.
Notes for -or- representing no sound
- factory
This is included here because it is questionable whether it can be regarded as a derivative of "factor". And in that it is (if only historically) so derived, the sense of "factor" in question is largely a businessman (sic - certainly, in the 16th century [when the word was coined], a man) of the past.
The Macmillan English Dictionary transcription and audio sample have this vowel sound, but a pronunciation with /ə/ is not uncommon. - mayor, mayoral, mayoralty, mayoress
It is arguable whether this -or- represents no sound. Rather, the "-ayor" spelling in these words represents the sound /eə/.
Notes for -or- representing /ʊ/
- Worcester, Worcestershire
The Macmillan English Dictionary does not list this word, although it does list the tradename Worcester Sauce. The link is to the Collins English Dictionary. - worsted
This is the noun (a sort of cloth). For the verb see under /ɜ:/.
Notes for -or- representing /əʊ/
- forecastle
This escapes the usual exclusion of "fore-" compounds because of its non-standard pronunciation. Reflecting this pronunciation (/'fǝʊksǝl/), the spelling "fo‘c‘sle" is often used.
