Jaded
Physically exhausted, worn out by effort. In Hiberno-English the bodily sense dominates: 'I'm jaded after the walk' means tired in the legs, not weary of life. Distinct from the standard English sense of bored or world-weary, which Irish speakers reach for with 'fed up' or 'scunnered' instead.
Etymology
From the noun 'jade' (a worn-out horse), itself possibly from Old Norse 'jalda' (a mare). The verb 'to jade' meant to tire out a horse; 'jaded' became the adjective. Standard English broadened the use to cover emotional exhaustion and cynicism; Hiberno-English narrowed it to keep the original physical sense as the dominant register. Both senses are documented, with the physical sense the older.
In a sentence
"We did the full eight kilometres - I'm absolutely jaded."
Historical notes
Jaded is a small case of Hiberno-English keeping the literal sense while standard English drifted to the metaphorical. A standard English speaker reading an Irish friend's text saying 'I'm jaded' might wonder what bored them; the Irish speaker means they cannot face another hill. The semantic narrowing is durable - Irish English has not picked up the standard English emotional-cynicism sense even as the rest of the language has.
