Of eight in a boat? (3)
I believe the answer is:
row
'a boat?' is the definition.
(thesaurus)
'of eight in' is the wordplay.
'of' becomes 'o''.
'eight' becomes 'rw' (I can't explain this - if you can you should believe this answer much more).
'in' is an insertion indicator.
'o' placed within 'rw' is 'ROW'.
Can you help me to learn more?
(Other definitions for row that I've seen before include "Quarrel; use oars" , "Barney - rank" , "Propel boat manually" , "Fight in a queue?" , "Line, tier" .)
