Thanks. Guessed as much. What I think I am missing is whether clues like the last seven letter one down only takes up six spaces so two letters go in one cell. Presumably these fit with the across similarly.
I nearly have a full grid too, but am struggling to fit in VET, TITIS and the answer to "Takes ill at sea" (which I thought was AILS but looking at the grid that must be wrong) with REALIST and ALARMIST. Any pointers please?
