Conversation

I feel like my study habits are really undisciplined lately.

Yeah, I can relate. It's hard to stay focused sometimes.

I need to find a way to be more organized and less undisciplined with my time.

Synonyms & Antonyms

Root Explanation

Undisciplined → It is formed from "un-" (meaning not) and "disciplined" (from Latin "disciplina", meaning instruction or training). The word "undisciplined" means not trained or lacking discipline.

Memory Tip

Think of 'not' ('un-') being added to 'trained' or 'instructed' ('disciplined') — that's why undisciplined means lacking training or control.
