Language making the disturbed hypnotist sit out (6)
I believe the answer is:
python
'language' is the definition.
(python is a programming language)
'the disturbed hypnotist sit out' is the wordplay.
'the disturbed' is an anagram indicator.
'out' is a deletion indicator.
'hypnotist' with 'sit' removed is 'hypnot'.
'hypnot' is an anagram of 'PYTHON'.
'making' acts as a link.
(Other definitions for python that I've seen before include "Large constricting snake" , "Type of snake" , "Large snake that strangles its prey" , "Snake that kills its prey by squeezing" , "Heavy-bodied snake" .)
