This article deals with the phonology and phonetics of Standard Modern Greek. For phonological characteristics of other varieties, see varieties of Modern Greek, and for Cypriot, specifically, see Cypriot Greek § Phonology.
Greek linguists do not agree on which consonants to count as phonemes in their own right, and which to count as conditional allophones. The table below is adapted from Arvaniti (2007, p. 7), who does away with the entire palatal series, and both affricates [t͡s] and [d͡z].
The alveolar nasal /n/ is assimilated to following obstruents; it can be labiodental (e.g. αμφιβολία [aɱfivoˈlia] 'doubt'), dental (e.g. άνθος [ˈan̪θos] 'flower'), retracted alveolar (e.g. πένσα [ˈpen̠sa] "pliers"), alveolo-palatal (e.g. συγχύζω [siɲˈçizo] 'to annoy'), or velar (e.g. άγχος [ˈaŋхos] 'stress').
