It is satirical when electronic programs, internet gateways initially go on strike (7)
I believe the answer is:
epigram
'it is satirical' is the definition.
The definition suggests a singular noun which matches the answer.
'electronic programs internet gateways initially go on strike' is the wordplay.
'initially' says to take the initial letters.
'go on' is a charade indicator (letters next to each other).
'strike' becomes 'ram' (I've seen this before).
The initial letters of 'electronic programs internet gateways' is 'epig'.
'epig'+'ram'='EPIGRAM'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for epigram that I've seen before include "Witty or sarcastic saying" , "Bon mot" , "Concise witty saying" , "Short witty remark" , "A clever witty saying" .)
