Inflections or morphemes attached either to the beginnings (prefixes), ends (suffixes), or middles (infixes) of words. Adding prefixes and suffixes to word roots is a feature of so-called agglutinating languages (those in which have a morphological system in which words as a rule are polymorphemic and where each morpheme corresponds to a single lexical meaning). One such example is Turkish (e.g.,’bakmak’, ‘bakıyorum’, ‘bakıceg˘im’, ‘bakıceg˘iz’).
