Postalveolar

Also flaps are used as basic rhotics in Japanese and Korean languages, although it is a lateral apical postalveolar flap.

Grammar Similarly, Slavic languages have extensive morphophonemic alternations in their derivational and inflectional morphology, including between velar and postalveolar consonants, front and back vowels, and between a vowel and no vowel.

The original outcomes of palatalization must have continued to be phonetically palatalized even after they had developed into alveolar postalveolar /etc. consonants.

These and the postalveolar sounds are typical of diminutives, which are used frequently in child language and motherese (mainly to show affection rather than size).
