Synonym discussion
Sense: noun/1
'Hart', 'stag', and 'buck' all refer to male deer, but they differ in species and register. 'Hart' is the most specific — it means a male red deer (Cervus elaphus) and is now primarily a literary or historical term. 'Stag' is the modern everyday word for any adult male deer, regardless of species, and is the best choice in general conversation and nature writing. 'Buck' refers to the male of smaller deer species such as roe or fallow deer, and is also used for male rabbits and kangaroos. 'Deer' itself is the broadest term covering both sexes and all ages. In practical terms: say 'stag' when you see a male deer in a park, say 'hart' only in historical fiction or poetry about red deer, and say 'buck' in American contexts for whitetail or mule deer.

Etymology
The word 'hart' comes from Old English 'heorot', meaning a stag or male deer. This traces back to Proto-Germanic '*herutaz', which is related to the Proto-Indo-European root '*ḱer-' meaning 'horn' — so a 'hart' is literally 'the horned animal'. The surname Hart originated as a nickname for someone thought to resemble a stag in speed, strength, or proud bearing.
