The adjective hydrophilic describes something that 'likes water' (from Greek hydros = water; philos = friend).

A hydrophilic molecule or portion of a molecule is one that typically is electrically polarized and capable of H-bonding, enabling it to dissolve more readily in water than in oil or other "non-polar" solvents.

Hydrophilic molecules can establish hydrogen bonds with water molecules (H₂O). This is favourable by thermodynamics and makes these molecules soluble in water.
