mixo-comb. form
Stress is usually determined by a subsequent element and vowels may be reduced accordingly; see e.g.
mixolimnion n.Origin: A borrowing from Greek. Etymon: Greek μιξο-.
Etymology: < ancient Greek μιξο- (in e.g. μιξολύδιος , μιξοπῦος , μιξοβάρβαρος : see below) < the base of μιγνύναι to mix (see mixed adj.2).Earliest attested in a small number of words loaned from or modelled on ancient Greek words, as mixolydian adj. (16th cent.), mixopyous adj., mixo-barbaric adj. (all 19th cent.); compare also Mix-Hellene n. English formations are found from the late 19th cent., combined with second elements ultimately of Greek origin. The position of the stress differs between compounds of mixo- in accordance with the general stress patterns of English. Contrastive stress may also give rise contextually to primary stress on the first syllable of the prefix in compounds where the stress ordinarily falls elsewhere.
