Desire knight to have bigger clothing (6)
I believe the answer is:
hunger
'desire' is the definition.
(hunger is a kind of desire)
'knight to have bigger clothing' is the wordplay.
I cannot really see how this works, but
'knight' could be 'n' (chess abbreviation) and 'n' is found in the answer.
'bigger' could be 'huger' ('huge' can be similar in meaning to 'big') and 'huger' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for hunger that I've seen before include "Aching need" , "Tummy-rumbling desire" , "Thirst" , "Consequence of food deprivation" , "Longing for food" .)
