While "pore" can be used as a verb (meaning to study something carefully) it's more commonly used as a noun referring to a tiny opening in the skin, or a hole in a surface.
There are a few words that are *near homophones* of "poor" in that they sound similar but have different spellings and meanings:
* pour (verb - to cause liquid to flow)
* power (noun - strength or influence)
* pore (verb - to think deeply or carefully)
It's important to note that the spelling and meaning of these words are distinct, and they are not true homophones of "poor".
