Sequences of adfixes (prefixes or suffixes) 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 linguistics are often sequences of prefixes of this type, though there may be debate over specific cases.
