1. Affixes that resemble suffixes but function differently:
* Derivational morphemes: These are affixes that change the meaning or grammatical category of a word, like "-ing" in "walking" or "-ness" in "happiness." While they are added to the end of a word, they often have a more complex interaction with the base word than simple suffixes.
* Clitics: These are words that are pronounced like suffixes but are grammatically independent. They often attach to the preceding word for phonetic reasons but have their own meaning and function, like the "n't" in "can't" or the "s" in "he's."
2. Pseudo-scientific jargon:
* It's possible the term is used in a non-standard way to refer to a specific phenomenon. In this case, providing more context about where you encountered the term would be helpful.
3. Misspelling or misunderstanding:
* It's also possible you are misremembering or misspelling a related term. Do you mean "pseudo words," "suffixoids," or something else entirely?
Please provide more context about where you encountered the term "pseudo suffixes" so I can provide a more accurate answer.
