In linguistic morphology, a transfix is a discontinuous affix which is inserted into a word root, as in root-and-pattern systems of morphology, like those of many Semitic languages. A discontinuous affix is an affix whose phonetic components are not sequential within a word, and instead, are spread out between or around the phones that comprise the root. The word root is often an abstract series of three consonants, though single consonant, biliteral, and quadriliteral roots do exist. An example of a triconsonantal root would be ḍ–r–b (ض ر ب) in Arabic, which can be inflected to create forms such as ḍaraba 'he beat' and yaḍribu 'he beats'. While triconsonantal roots are widely considered to be the most common state, some linguists posit that biliteral roots may in fact be the default, though at least one scholar is skeptical of the legitimacy of these claims. Transfixes are placed into these roots in assigned positions, dictated by templates which are tied to the specific meaning of a given inflection or derivation. The transfixes in the examples above are –a–a–a and ya––i–u. Transfixes are different from prefixes, suffixes, and infixes in that a complete transfix is the entire structure which is placed into a root. A transfix is not a combination of prefixes, suffixes, and infixes, but its own unique structure which is split through a word. Similarly, another difference transfixes hold from other affixes is that the individual components of the transfix are meaningless on their own. If we look again at ḍaraba, the components of the –a–a–a transfix do not encode any meaning individually. Only together do they create the tense meaning. The following are examples of verb inflection in Maltese, noun derivation in Arabic, and noun pluralization in Hausa, all three of which are Afro-Asiatic languages. {| class="wikitable" |+ Maltese indicative inflections of the root q–t–l: Perfect and Imperfect ! colspan="3" | ! colspan="2" | Perfect ! colspan="2" | Imperfect |- ! rowspan="2" | 1stperson ! colspan="2" | Singular | qtilt || "I killed" || noqtol || "I kill" |- ! colspan="2" | Plural | qtilna|| "We killed" || noqtlu || "We kill" |- ! rowspan="2" | 2ndperson ! colspan="2" | Singular | qtilt || "You killed" || toqtol || "You kill" |- ! colspan="2" | Plural | qtiltu || "You killed"|| toqtlu || "You kill" |- ! rowspan="3" | 3rdperson ! rowspan="2" | Singular !
