Synonym discussion
Sense: noun/1
All three words involve exposure to the sun, but they highlight different aspects. 'Tanning' focuses on the darkening of the skin — either as a desired result ('She goes to the beach for tanning') or as an unintended effect ('the tanning of outdoor workers'). 'Sunbathing' describes the activity itself: lying or sitting in the sun, typically for pleasure or relaxation, whether or not the person actually darkens. 'Bronzing' is more cosmetic and aspirational — it emphasises achieving an attractive golden-brown colour, often through the use of lotions or sprays in addition to sunlight. You would say 'I went sunbathing yesterday' (activity), 'I noticed some tanning on my arms' (result), and 'This lotion gives a natural bronzing effect' (aesthetic quality).

Etymology
The word 'tanning' comes from the verb 'tan', which originally meant 'to convert animal hide into leather'. This verb entered English from Old English 'tannian', which came from Medieval Latin 'tannare' ('to tan leather'), which in turn came from 'tannum' ('crushed oak bark' — the material used in the ancient tanning process). The sense of skin darkening in the sun developed around the 1700s, probably because the colour change reminded people of the colour that leather takes on during the tanning process. The informal sense of 'a beating' appeared in the 1800s, likely because a beating turns the skin red in a way that resembles the colour changes of leather tanning.
