S?A?L
The answer appears to be SCAIL i.e. sail plus C from Caithness, however my dictionary doesn't show this word. Any thoughts.?
Thank you mamya,chrisg and jazzgirl. I started trying Cryptics some five years back and went to a group to learn how. The guy running it suggested getting a Collins dictionary but I went for a Shorter OED. I regret this decision 'scail' is not in it and many other words besides in the past. Can you tell me which Collins you are using and I will treat myself to an early Xmas present. thanks again p.
