Samoan Malayo-Polynesian Samoyedic Uralic San Khoisan Sandawe Khoisan sandhi [Old Indic ‘putting together’]

Term taken from Old Indic grammar ( Sanskrit) for the merging of two words or word forms and the resulting systematic phonological changes. Internal sandhi involves two morphemes within a word; external sandhi takes place between two consecutive words. An example of the latter is the variation of the indefinite article in English: a with a following consonant and an before a vowel (a book vs an egg).
