The word that does not have an affix is paint.
What is an affix?
An affix is a morpheme that is joined to a word stem to create a new word or word form in linguistics. Affixes can be derived, like the English prefix and suffix -ness, or they can be inflected, like the English plural -s and past tense -ed.
Paint is a stem word as it does not have any prefix or suffix attached to it. It would have an affix if the word was "paint-ed" or "paint-s"
Other words "marble-s", "open-ed", and "under-water" have affix attached to it.
Thus, the only word given that does not have an affix is paint.
