Starts to settle into the seat (4)
I believe the answer is:
sits
'starts to settle into the seat' is the definition.
I can't judge whether this defines the answer.
'starts to settle into the seat' is the wordplay.
'starts to' says to take the initial letters.
The first letters of 'settle into the seat' is 'SITS'.
Can you help me to learn more?
