What a state, nothing on line 1 and only x2 letters by line 3. Didn't think it would accept my fourth line ( being a naughty word ...giggle) but it gave the answer away. A 5.
I think they are taking the p155. Deliberately selected to ensure failure. My accidental entry on line 4 left me speechless. No clues to be found here.
5 After line 4 I so nearly gave up, didn’t have the energy or inclination… But Mrs O got it in 4 so spurred me on… HEAD SCRATCH GRRRRRRR
Every new noun under investigation for this one as never heard of it....... The pronunciation even sounds foreign. A silly choice of word for the majority to fail on when surely there's thousands of better options A 3 for me but purely luck.
