Conversation

I tried that new study method, but it felt really ineffective for me.

Really? I heard it works well for some people.

Yeah, I think I need something more engaging, or it just feels ineffective.

Synonyms & Antonyms

Root Explanation

Ineffective → It is formed from "in-" (meaning not) and "effect" (from Latin "effectus", meaning to accomplish or bring about) and the suffix "-ive" (meaning having the nature of). The word "ineffective" means not having the ability to bring about a desired effect or result.

Memory Tip

Think of 'not' ('in-') being combined with 'to accomplish' ('effect') — that's why ineffective means something that does not accomplish its intended result.
