Not deserving respect or admiration; considered to be of low moral standards.

Unrespectable → It is formed from "un-" (meaning not) and "respectable" (from Latin "respectabilis", meaning worthy of respect). The word "unrespectable" means not worthy of respect or disreputable.
Think of 'not' ('un-') being added to 'worthy of respect' ('respectable') — that's why unrespectable means not deserving respect.
