Synonym discussion
Sense: noun/2
All five words describe stability or lack of variation, but they highlight different aspects. Consistency (the most general and common) means acting or occurring the same way over time — a basketball player who scores 20 points every night has consistency. Uniformity stresses identicalness across items or members — school uniforms create uniformity, but a team could have uniform outfits yet inconsistent performance. Regularity focuses on even intervals or repeated patterns — a runner who trains every morning shows regularity, even if their speed varies. Constancy implies unwavering reliability, often with emotional weight — a friend who is always there for you shows constancy. Coherence is about ideas or parts fitting together logically — a well-argued essay has coherence, but a writer who always uses the same sentence structure has consistency, not necessarily coherence. Use consistency when you mean reliable similarity over time; use uniformity when the focus is on sameness across a group; use regularity for repeated occurrence; use constancy for dependable loyalty; and use coherence for logical connectedness.

Etymology
From Latin 'consistentia', meaning 'a standing together' or 'firmness of material', formed from 'com-' (together) and 'sistere' (to stand or place). The word first entered English in the late 1500s with the physical meaning — how firmly a substance holds together. By the mid-1600s, it had broadened to describe behaviour that 'stands together' without contradiction, giving us the modern abstract sense of people or things being reliably the same over time.
