Maybe this problem is a bit too trivial for some people. I could not find any dictionary giving me a pronunciaiton for the word 'pluriharmonic'. Google does not work, either. Will someone be kind enough to give me a pronunciation for this word? It is a word from mathematics. I guess since it is a compound word, 'pluri-harmonic' may be its correct form. So will someone give me some information on the 'pluri' part? How is it pronounced? Thank you very much!
The entire word may not be in online dictionaries, but its parts certainly are. OxfordDictionaries.com has:
pluri- /ˈplʊəri/, combining form: several
harmonic /hɑːˈmɒnɪk/, adjective: relating to a harmonic progression
So: /ˈplʊəri/ /hɑːˈmɒnɪk/, or in simplified form: plu-ri-hahr-mon-ik
As a classical compound, it's not necessarily hyphenated, but looking at other words compounded from pluri- (pluripotent, plurilateral, etc.), it appears that it is not:
OED doesn't have this, but it does have others to model your pronunciaiton on. For example pluriflorous
Brit. /ˌplʊərɪˈflɒrəs/ , /ˌplɔːrɪˈflɒrəs/ , U.S. /ˌplʊrəˈflɔrəs/
Brit. /ˌplʊərɪˈparᵻti/ , /ˌplɔːrɪˈparᵻti/ , U.S. /ˌplʊrəˈpɛrədi/
Probably the prefix is /'plərə/, or /'plʊrə/ in careful speech; almost certainly it wouldn't end in /i/ in a compound.
The initial /h/ in harmonic may or may not be pronounced, since it's stressed on the second syllable like historic, and prefixation wouldn't shift its stress.
So, all together then, if it were a frequently pronounced word, it would be /'plərəhar'manək/, with two stresses, one of which might be slightly louder than the other -- but which one would vary.
But it's obviously made up from classical roots, so anybody might well pronounce it any way at all, since it's not a common word to most readers.
Pronounce 'pluri' so that it rhymes with 'furry'.
