There isn't really anywhere to look to find them. Just put your crossing letters into a word finder like chambers word wizard or universal crossword solver...there weren't many choices for most of them . Then just check any definitions to see where they "originate from"
Which are you stuck on?
Thank you so much. Thanks to Chambers Word Wizard I have them all now.
I have to confess that Chambers Word Wizard is new to me and what a powerful weapon.
