null morpheme

Other terms for null morpheme are zero morpheme") and ghost morpheme") . In languages that show the above distinctions, it's quite common to employ null affixation to (not) mark singular number, present tense and third persons (English is unusual in its marking of the third person singular with a non-zero morpheme, by contrast with a null morpheme for others). It's also frequent to find null affixation for the least-marked cases (the nominative in nominative-accusative languages, and the absolutive in ergative-absolutive languages). In most languages of the world these are the affixes that are realized as null morphemes. But in some cases roots may also be realized as these. For instance, Russian word вы-Ø-ну-ть (vynut', to take out) consists of one prefix (вы-), one zero root (-Ø-), one suffix (-ну-), and one postfix (-ть) [1]. A basic radical element plus a null morpheme is not the same as an uninflected word, though usage may make those equal in practice. REF This article has no reference(s) or source(s) .
