Hi Novice,
The removed words tell what to do. eg 1 across the removed word is EFFORTS but read as EF for TS as an instruction to change the entry. The longer and shorter entries are indicated by eg 15 across JUNKY read as junk Y or eg 3 down ADDICT read as add ICT.
I'm struggling with the SW corner and need a couple in the NE corner - any help gratefully appreciated
