Some ornate style that makes us irritable (5)
I believe the answer is:
testy
'irritable' is the definition.
(testy can mean irritable or annoyed)
'some ornate style that' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'TESTY' is hidden in the letters of 'ornate style that'.
'makes us' is the link.
(Other definitions for testy that I've seen before include "Quick to anger" , "Easily annoyed" , "snappy" , "Grumpy" , "Captious" .)
