Alas, elite worried, so worried (3,2,4)
I believe the answer is:
ill at ease
'worried' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'alas elite worried' is the wordplay.
'worried' is an anagram indicator (worry can mean to interfere with or disturb).
'alas'+'elite'='alaselite'
'alaselite' anagrammed gives 'ILL-AT-EASE'.
'so' acts as a link.
Can you help me to learn more?
(Other definitions for ill at ease that I've seen before include "awkward" , "Unable to relax" , "discomfited" , "Unsettled, anxious" , "Unsure and constrained in manner" .)
