Frustrating, right? That’s incoherence in action, and it’s the word we’re exploring today in our SAT vocabulary lesson.
Word type: Incoherent is an adjective.
Meaning: Incoherent means lacking logical connection, consistency, or intelligibility; confused, rambling, or disjointed.

Word history: The term incoherent comes from the Latin word incoherentem, which means not sticking together.
It’s composed of the prefix in meaning not, and coherent, from the Latin cohaerere, meaning to stick together or to be closely connected.
