pony

The journey of 'pony' begins with the Latin word 'pullus', a general term for the young of any animal. This evolved into the Late Latin 'pullanus', specifically for a young horse or foal. Adopted into Old French as 'poulain', it later took a diminutive form 'poulenet' in Scots, signaling something small and endearing. This term was borrowed into English, where its spelling simplified to 'pony', perfectly capturing its core meaning: a small horse. The semantic shift from a general 'young animal' to a specific 'small breed of horse' illustrates a common path of meaning specialization.

The word 'pony' is a simplex loanword. Its direct origin is mid-17th century Scottish English 'powny', likely from obsolete French 'poulenet', a diminutive of 'poulain' (foal), which itself derives from Late Latin 'pullanus' (young animal), from Latin 'pullus' (young of an animal, foal, chick).
