From what I've seen so far, roots never end in a suffix or start with a prefix. I've reasoned that it should be that way:
- If roots contained affixes, it would be confusing and give the impression that something smaller is the actual root.
- Esperanto has a large alphabet and even with all prefixes and suffixes disallowed from roots, there should still be more than enough possible roots.
I won't make that assumption though. Maybe those kinds of roots do exist. I have an argument for that too:
- Esperanto has roots based on words in other languages. If a root happened to contain an affix, it could have been easier to keep it like that as an exception rather than to come up with an entirely new root to convey that meaning.
Are there any roots that end in a suffix or start with a prefix? If so, why are they like that?
