The answers have to be Tolkienesque. but the clues may not be .. I meant that the answer might contain SIN COS or TAN as an element - and a lot of ME words have Sin or tan elements - sindarin, atani..however looking closer and with hints I now recall sin cos and tan are in full Sine, cosine,and tangent. Dislocation suggests maybe an anagram but I can't think of anything.
Oh I don't own either but I have the JRRT artist and illustrator and I remember seeing bears other than the NPB. Just about all my Tolkien books are in store atm
