• Polyphagy — feeding on many kinds of food (f.e. all (or almost all) the species of a single plant family)
• Phytophagy — the eating of plants
• Xylophagy — the eating of wood
• Foliophagy — the eating of leaves

Phagy can also be used to name eating in a specified manner, normal or abnormal (for example dysphagia, a dysfunction of deglutition).

The term comes from Greek language phagein, to eat; with Indo-European language roots in bhag.
