Really fond of group of teachers here (4)
I believe the answer is:
into
'group of teachers here' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'really fond of' is the wordplay.
'really fond' becomes 'int' (I am not sure about this - if you are sure you should believe this answer much more).
'of' becomes 'o''.
'int'+'o'='INTO'
Can you help me to learn more?
(Other definitions for into that I've seen before include "A fan of" , "Curious about" , "Liking" , "Taking an active and lively interest (in something)" , "Keen on (informal)" .)
