Chaps keen to set out computer jargon (11)
I believe the answer is:
technospeak
'computer jargon' is the definition.
I know nothing about this answer so I can't judge whether this works.
'chaps keen to set' is the wordplay.
'set' indicates anagramming the letters (instruction to set the letters).
'chaps'+'keen'+'to'='chapskeento'
'chapskeento' anagrammed gives 'TECHNOSPEAK'.
'out' is the link.
Can you help me to learn more?
(Another definition for technospeak that I've seen is " Incomprehensible scientific jargon".)
