Appear to give notice before end of term (4)
I believe the answer is:
seem
'appear' is the definition.
(I know that appear can be written as seem)
'notice before end of term' is the wordplay.
'notice' becomes 'see' (notice can mean to spot or see).
'before' means one lot of letters go next to another.
'end of' indicates one should take the final letters.
The last letter of 'term' is 'm'.
'see'+'m'='SEEM'
'to give' is the link.
(Other definitions for seem that I've seen before include "Appear, give impression of being" , "Come across as" , "Appear, look" , "Appear to the eye" .)
