Domestic intercepted by oddly terse host (6,1)
I believe the answer is:
maitre d
'host' is the definition.
(I've seen this before)
'domestic intercepted by oddly terse' is the wordplay.
'domestic' becomes 'maid' (maid is a kind of domestic).
'intercepted by' indicates putting letters inside (I've seen this in other clues).
'oddly' means one should take alternating letters (letters in the odd-numbered positions are used).
The alternating letters of 'terse' are 'tre'.
'maid' placed around 'tre' is 'MAITRE D''.
(Other definitions for maitre d that I've seen before include "a man to supervise dinner" , "Host" , "one waiting" , "Head waiter" .)
