IPA: /ɪnˈɛkspɜrt/
KK: /ɪnˈɛkspɜrt/
Someone who is not skilled or knowledgeable in a particular area or activity.

Inexpert is formed from "in-" (meaning not) and "expertus" (from Latin, meaning experienced or skilled). The word describes someone who is not skilled or lacks expertise in a particular area.
Think of 'not' ('in-') being combined with 'skilled' ('expertus') — this helps you remember that inexpert means lacking skill or experience.
