Element of technical language judge avoided (5)
I believe the answer is:
argon
'element' is the definition.
(argon is a kind of element)
'technical language judge avoided' is the wordplay.
'technical language' becomes 'jargon' (I've seen this before).
'judge' becomes 'j'.
'avoided' indicates named letters should be taken away.
'jargon' with 'j' taken out is 'ARGON'.
'of' acts as a link.
(Other definitions for argon that I've seen before include "Chemical element" , "Inert gas used in light bulbs" , "something inert and insubstantial" , "17 [GAS]" , "Inert gas in atmosphere" .)
