The vast majority are Greek- and Latin-derived morphemes added to modify the "meaning, grammatical function, or part of speech" (googly AI Overview)

...English has almost no true infixes and those it does have are marginal. Most are heard in colloquial speech;[1] although there are other examples, such as in technical terminology, these examples are often more accurately described as tmesis.
