Start with the head: head, hair, face, eyes, ears, nose and mouth. Simple, but the pronunciation of “teeth” and “tongue” often trips people up.
Torso and limbs: shoulders, chest, back, arms, hands, fingers, legs, knees and feet (plural of foot). Watch the irregular plurals.
To talk about pain, the structure changes: “My back hurts” or “I have a headache/stomachache”. Worth memorizing these ready-made combos.
In practice
Irregular pluralfoot → feet, tooth → teeth.
Pain“I have a sore throat.”
Idiom“Break a leg!” = good luck (not literal!).
