Editing Infix (section)

[[Tmesis]], the use of a [[lexical word]] rather than an affix, is sometimes considered a type of infixation. These are the so-called "expletive infixes", as in ''abso-bloody-lutely''. Since these are not affixes{{Citation needed|date=May 2022}}, they are commonly disqualified from being considered infixes.

Sequences of adfixes ([[Prefix (linguistics)|prefix]]es or [[suffix (linguistics)|suffix]]es) do not result in infixes: an infix must be internal to a [[word stem]]. Thus, the word ''originally,'' formed by adding the suffix ''-ly'' to ''original,'' does not turn the suffix ''-al'' into an infix. There is simply a sequence of two suffixes, ''origin-al-ly.'' In order for ''-al-'' to be considered an infix, it would have to have been inserted in the non-existent word ''*originly.'' The "infixes" in the tradition of [[Bantu languages|Bantu]] linguistics are often sequences of prefixes of this type, though there may be debate over specific cases.

The [[Semitic languages]] have a form of ''[[ablaut]]'' (changing the vowels within words, as in English ''sing, sang, sung, song)'' that is sometimes called infixation, as the vowels are placed between the consonants of the root. However, this interdigitation of a discontinuous root with a discontinuous affix is more often called ''[[transfix]]ation''.

An ''[[interfix]]'' joins a [[compound word]], as in ''speed-o-meter''.
