Coach full of sailors feels very hot (5)
I believe the answer is:
burns
'feels very hot' is the definition.
I can't tell whether this definition defines the answer.
'coach full of sailors' is the wordplay.
'coach' becomes 'bus' (synonyms).
'full of' means one lot of letters goes inside another.
'sailors' becomes 'RN' (abbreviation for Royal Navy).
'bus' enclosing 'rn' is 'BURNS'.
Can you help me to learn more?
(Other definitions for burns that I've seen before include "Cremates -- Scottish poet, d.1796" , "Is on fire" , "is full of passion" , "feels strong emotion" , "Scots poet" .)
