Synonym discussion
Sense: adverb/1
All four words describe behaviour that lacks politeness, but they differ in tone and scope. Impolitely is the most general and neutral term — it covers any failure to follow social etiquette, from forgetting to say 'thank you' to raising one's voice. Disrespectfully is stronger and more personal; it suggests a deliberate attack on someone's status or authority, such as ignoring a teacher or mocking a boss. Discourteously is the most formal and old-fashioned of the group; it appears more in written descriptions of minor social failures (e.g. failing to hold a door) than in everyday speech. Bluntly focuses on directness rather than rudeness — speaking without softening the message, which may or may not offend. For example: 'She bluntly told him his work was poor' (honest, not necessarily rude) versus 'She rudely shouted at him in front of everyone' (clearly disrespectful).
Etymology
From the adjective 'rude' (meaning 'rough, unskilled, uncivil') plus the adverb-forming suffix '-ly'. The adjective entered English from Old French 'rude', which came from the Latin 'rudis', meaning 'rough, unpolished, or untrained'. The original sense of 'rudely' in Middle English was 'in a rough or unskilled manner' (now sense 4). The social meaning of 'impolitely' (sense 1) developed in the 1600s as the idea of 'rudeness' shifted from a lack of refinement to a lack of good manners. The intensifying British use in 'rudely healthy' (sense 5) is the most recent, appearing in colloquial speech from the 1800s onward.
