Old 'tec was agitated: came out in this? (4,5)
I believe the answer is:
cold sweat
'came out in this?' is the definition.
The definition suggests a singular noun which matches the answer.
'old 'tec was agitated' is the wordplay.
'agitated' is an anagram indicator.
'old'+'tec'+'was'='oldtecwas'
'oldtecwas' is an anagram of 'COLD SWEAT'.
Can you help me to learn more?
(Other definitions for cold sweat that I've seen before include "Symptom of nervousness or illness" , "Chilled perspiration" , "nervous reaction" , "Chilly perspiration brought on by fear" , "sign of fear" .)
