Very busy swot starting late, middle in Latin (6)
I believe the answer is:
rammed
'very busy' is the definition.
I can't judge whether this definition defines the answer.
'swot starting late middle in latin' is the wordplay.
'swot' becomes 'cram' (synonyms).
'starting late' means to remove the first letter (the word begins later than normal).
'middle in latin' becomes 'med' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'cram' with its initial letter taken off is 'ram'.
'ram'+'med'='RAMMED'
Can you help me to learn more?
(Other definitions for rammed that I've seen before include "Struck forcibly" , "impacted" , "Ran into violently" , "Hammered" , "Bashed or drove into" .)
