Infix

 

an affix, inserted within the stem in word formation or word inflection. The infix is an important means of affixation in the Indonesian languages, for example: in Tagalog s-um-ulat (“to write”) and s-in-ulat (“was written”) are derived from sulat (“writing”). The so-called nasal infix in Indo-European languages—in Latin, vic-i (“I conquered”) and vi-n-co (“I am conquering”)—is of a more debatable nature, since it does not have a definite meaning. Russian has alternations that originated in the Indo-European nasal infix: Russian lech’—liagu (“to lie”— “I’ll lie”) and sest’—siadu (“to sit”—“I’ll sit”) from Indo-European leg-ti—le-n-g-ō and sed-ti—se-n-d-ō.
