Intruders somewhat disrespectful (4)
I believe the answer is:
rude
'disrespectful' is the definition.
(I've seen this in another clue)
'intruders somewhat' is the wordplay.
'somewhat' indicates the answer is hidden within the clue.
'RUDE' is hidden in the letters of 'intruders'.
(Other definitions for rude that I've seen before include "Impolite; basic" , "Uncivil" , "dirty" , "Uncultivated" , "Impolite; unpolished" .)
