Affixation is a morphological process in which a bound morpheme—an affix—is attached to a base, stem, or word to form a new lexeme or a grammatical word form ^[1]. Depending on its position relative to the base, an affix may be a prefix, suffix, infix, circumfix, or another language-specific type; its attachment may encode derivational meanings or categories, such as changes in lexical category or meaning, or inflectional grammatical information, such as number, tense, case, or agreement ^[1][2]. Affixation is distinguished from compounding, which combines two or more lexical bases, and from conversion, which changes a word’s grammatical function without overt morphological marking; its defining property is the addition of a non-independent morphological element to a host ^[2].
