One and all turned guy a little edgy (3,2,4)
I believe the answer is:
ill at ease
'a little edgy' is the definition.
I can't judge whether this defines the answer.
'one and all turned guy' is the wordplay.
'one' becomes 'i' (Roman numeral).
'and' says to put letters next to each other.
'turned' says the letters should be written backwards.
'guy' becomes 'tease' (guy can mean to tease or make fun of).
'all' backwards is 'lla'.
'i'+'lla'+'tease'='ILL-AT-EASE'
Can you help me to learn more?
(Other definitions for ill at ease that I've seen before include "wound up" , "discomfited" , "awkward" , "Unsettled, anxious" , "Unsure and constrained in manner" .)
