Conversation

Have you ever used a hydrometer to check the strength of your homebrew?

No, I haven't! What does it do exactly?

It measures the specific gravity of the liquid, which helps you understand its alcohol content.

That sounds really useful! I might need to get one for my next batch.

Root Explanation

Hydrometer → It is formed from "hydro-" (from Greek "hydor", meaning water) and "-meter" (from Greek "metron", meaning measure). The word refers to an instrument that measures the density or specific gravity of liquids, particularly water.

Memory Tip

Think of 'water' ('hydro-') being 'measured' ('-meter') — that's what a hydrometer does.
