Root Explanation
Inconsideration → It is formed from "in-" (meaning not) and "consideration" (from Latin "consideratio", meaning careful thought). The word refers to a lack of careful thought or regard for others.
Memory Tip
Think of 'not' ('in-') showing 'careful thought' ('consideration') — that's why inconsideration means a lack of thoughtfulness.
