What does breathing mean?
Breathing refers to the continuous physiological process by which air is drawn into the lungs and expelled again — what scientists call respiration. It is the present participle of the verb 'breathe' but also stands independently as a noun naming that activity itself, whether calm and unconscious or laboured and audible, as in 'heavy breathing'. Because breathing sustains life without conscious effort, the word carries connotations of vitality, calm, and rhythm: practices like deep breathing are associated with relaxation and mindfulness. Figuratively, 'breathing' extends to mean any brief reprieve, most often in the fixed expressions 'breathing space' or 'breathing room', which describe a pause or margin of freedom between pressures. The word appears constantly in medical, athletic, musical (for phrasing), and everyday speech, making it both clinically precise and warmly familiar.

Present participle of 'breathe': to draw air into and expel it from the lungs.

You take about 20,000 breaths a day — and 'breathing' is one of only two words in English where the '-thing' suffix is actually part of an older verb form.

Etymology of breathing
'Breathing' derives from the Old English verb 'brǣthan', meaning to breathe or exhale, itself formed from the noun 'brǣth' (breath), which shares Germanic roots with related words in other Germanic languages. The verb was reinforced in Middle English by association with Old Norse 'draga' constructions and by analogy with other verbs ending in '-ethe'. Its figurative sense of a pause or rest developed later, giving rise to phrases like 'breathing space' from at least the seventeenth century onward.
