Containing no water or describing a chemical state without water molecules; anhydrous.
From Greek 'an-' (without) + 'hydro' (water) + '-ic' (relating to). It's a chemistry term describing substances in their dry form without water of hydration.
Anhydric chemicals are treasured in laboratories because water can ruin delicate reactions—chemists carefully store anhydric compounds in sealed containers to keep them bone-dry!
