Why this word

guess

Hypothesize implies an educated, testable conjecture; guess is informal and lacks scientific rigor

assume

Assume takes something as given without testing; hypothesize proposes something specifically for verification

speculate

Speculate is more casual and doesn't necessarily involve testable predictions like hypothesize does

Usage tip

Use when proposing testable explanations. Adds scientific rigor to speculation and implies intention to verify.

Etymology

Greek: hypothesis (hypo- 'under' + thesis 'placing')
