Which combining form means 'air, lungs'?

Pneum/o

Pharyng/o

Scler/o

Pneumum/o

Pneum/o- carries the idea of air or gas and is the combining form used when talking about air in general as well as things related to the lungs. You’ll see it in terms like pneumothorax (air in the chest) and pneumonia (a lung condition). The other forms point to different structures or concepts: pharyng/o is the pharynx, scler/o means hard or relates to the sclera, and pneumum/o isn’t a standard medical combining form. So the form that best conveys “air, lungs” is pneum/o-.
