I heard that Jack is really into that new game; he’s been playing non-stop.

Yeah, I noticed. It’s almost like he’s monomaniacal about it.

Root Explanation

Monomaniacal → It is formed from "mono-" (from Greek "monos", meaning single or alone) and "mania" (from Greek "mania", meaning madness or obsession) and the suffix "-cal" (indicating relating to). The word describes a state of being obsessed with a single idea or subject.

Memory Tip

Think of being 'alone' ('mono-') in your 'madness' ('mania') about one specific thing — that's what monomaniacal means.
