Applaud - yes, one goes wild, see (4,4,2)
I believe the answer is:
clap eyes on
'see' is the definition.
(thesaurus)
'applaud yes one goes wild' is the wordplay.
'applaud' becomes 'clap' (synonyms).
'goes wild' indicates anagramming the letters.
'yes'+'one'='yesone'
'yesone' is an anagram of 'eyeson'.
'clap'+'eyeson'='CLAP EYES ON'
(Other definitions for clap eyes on that I've seen before include "Spot" , "Catch sight of" .)
