Initial description of the Harrier jet for example (4)
I believe the answer is:
vtol
'initial description' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'the harrier jet for example' is the wordplay.
I cannot really understand how this works, but
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
The remaining letters 'vol' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Another definition for vtol that I've seen is " aircraft?".)
