Turkic
Turkic notes
- Based at least on Turkish (and a brief survey of other Turkic languages) it does not seem likely there is much of relevance in this family, where the morphology is highly regular (though not unaffected by morphophonological rules). Turkish shows some minor irregularity which is lexically highly restricted. For example, there are a dozen verbs with an unpredictable vowel in the aorist suffix (e.g. dön-er 'turns' and yap-ar 'does' are regular, while gör-ür 'sees' and san-ɪr 'thinks' are exceptional; Lewis 1967: 116). Some nouns undergo lexically specified deletion of a stem-final consonant when followed by some of the case markers, e.g. koyun 'bosom.nom' ~ koyn-u 'bosom-acc' (compare koyun 'sheep.nom' ~ koyun-u 'sheep-acc').
