Crossword Genius

Andy and one other become cross (7)

Ross

I believe the answer is:

annoyed

'cross' is the definition.
(thesaurus)

'andy and one other' is the wordplay.
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'other' is an anagram indicator.
'andy' put after 'one' is 'oneandy'.
'oneandy' is an anagram of 'ANNOYED'.

'become' is the link.

(Other definitions for annoyed that I've seen before include "Irate" , "Upset" , "Anodyne (anag.)" , "'Irritated, impatient (7)'" , "Vexed, irritated" .)

I've seen this clue in The Telegraph.
