Glossing
When glossing, it is conventional to set off infixes with ⟨angle brackets⟩, rather than the hyphens used to set off prefixes and suffixes:
- sh⟨izn⟩it, saxo⟨ma⟩phone, pi⟨pe⟩coline
Compare:
- origin-al-ly
which is a suffix -ly added to the word original, which is itself a suffix -al added to the root origin.
