Unconsidered → It is formed from "un-" (meaning not) and "consider" (from Latin "considerare", meaning to think about or reflect upon). The word "unconsidered" means not thought about or not taken into account.
Think of 'not' ('un-') thinking about something ('consider') — that's why unconsidered means something that hasn't been thought about.
