I love unusual words, and this (and its predecessor
Foyle's Philavery) is the kind of book I would expect to love. However it falls short of that for me. The main issue for me, although admittedly this second volume does not suffer quite so much in this way as the first does, is that I would like to see more words which you might have a finite chance of actually using in a lifetime, rather than simply words you might only ever have a chance of using in a game of Scrabble. Examples: gue - a kind of viol formerly played in Shetland; tutty - crude zinc oxide.
Funnily enough, Foyle says in his introduction to the earlier book that his mother-in-law coined the word "philavery" whilst the two of them were playing Scrabble, which is perhaps a bit of a giveaway.
I far more enjoyed the witty
Superior Person's Book of Words series of books to these.
