Less deserving of respect or attention than someone or something else.

Unworthier → It is formed from "un-" (meaning not) and "worthy" (from Old English "weorðig", meaning having worth or value) and the comparative suffix "-er" (indicating a higher degree). The word "unworthier" means not having worth to a greater extent than something else.
Think of 'not' ('un-') and 'having worth' ('worthy') — when something is 'unworthier', it means it lacks worth even more than another.
