'blunt-snouted' is a modern English compound formed from the adjective 'blunt' and the noun 'snout', where 'blunt' (Middle English 'blunt') meant 'dull, rounded' and 'snout' (Old English 'snūta') meant 'nose or projecting mouthpart'.

'blunt' existed in Middle English as 'blunt' and 'snout' comes from Old English 'snūta'; these elements were combined in later English to create the descriptive compound 'blunt-snouted'.

Initially the elements referred separately to a 'dull/rounded' quality and the 'nose' or 'snout'; combined, they have come to mean 'having a blunt (short, rounded) snout' in modern usage.
