Root Explanation

Expertise → It is formed from "expert" (from Latin "expertus", meaning experienced or skilled) and the suffix "-ise" (meaning to make or to become). The word "expertise" refers to the state of being skilled or knowledgeable in a particular area due to experience.

Memory Tip

Think of someone who is 'experienced' ('expertus') in a field, and the '-ise' suggests a state of being. This helps you remember that expertise means having a high level of skill or knowledge.
