Root Explanation

Conscientious → It is formed from "con-" (meaning with) and "sciens" (from Latin "scire", meaning to know). The word describes someone who is aware and diligent in their duties, acting with a sense of responsibility and care.

Memory Tip

Think of being 'with knowledge' ('con-' means with and 'sciens' relates to knowing) — this helps you remember that conscientious means being careful and responsible in what you do.
