Having permanent tenure, is unconstrained and starts heckling other lecturers disgracefully (8)
I believe the answer is:
freehold
'having permanent tenure' is the definition.
I can't tell whether this definition defines the answer.
'unconstrained and starts heckling other lecturers disgracefully' is the wordplay.
'unconstrained' becomes 'free' (similar in meaning).
'and' means one lot of letters go next to another.
'starts' says to take the initial letters.
The first letters of 'heckling other lecturers disgracefully' is 'hold'.
'free'+'hold'='FREEHOLD'
'is' is the link.
Can you help me to learn more?
(Other definitions for freehold that I've seen before include "System of property ownership" , "property one can dispose of at will" , "Property to keep" , "Type of tenure" , "Unencumbered property, without a lease" .)
