Raid carried out without water (4)

Ross

I believe the answer is:

arid

I'm a little stuck... Click here to teach me more about this clue!

'without water' is the definition.
(I've seen this before)

'raid carried out' is the wordplay.
'raid' can be anagrammed to 'ARID'.
But, I am not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for arid that I've seen before include "Dry and withered" , "(Of an area) very dry" , "Drought-hit" , "Very dry, having little rain" , "Dry, devoid of interest" .)
