っぽいHaving a quality; prone to
っぽい casually describes something as noticeably resembling a certain quality, containing a lot of something, or tending to behave in a certain way. The exact meaning depends on the word it attaches to.
Three common readings
With a person or thing, the suffix can mean “having the quality of” or “resembling.” With substances such as water or dust, it can suggest that too much of that substance is present. With a verb stem, it usually describes a person or thing as prone to that action or change.

Inflecting the completed word

Changing the ending
Broader tendency versus visible appearance
っぽい is conversational and covers resemblance, abundance, and recurring tendencies. By contrast, げ is more limited and describes an outwardly visible appearance, especially an apparent emotion; it forms a na-adjective.
