Clasp ring in ancient stone tower up north (6)
I believe the answer is:
brooch
I believe this clue is a quadruple definition!!
'clasp' is the first definition.
(synonyms)
'ring' is the second definition.
(thesaurus)
'in ancient stone' is the third definition.
'brooch' can be an answer for 'stone' (thesaurus). I'm not sure about the 'in ancient' bit.
'tower up north' is the fourth definition.
'brooch' can be an answer for 'tower' (I have seen 'prehistoric tower' mean 'brooch' so perhaps 'tower' could also mean 'brooch'). I am unsure of the 'up north' bit.
Can you help me to learn more?
(Other definitions for brooch that I've seen before include "Ornamental hinged pin with clasp" , "Jewellery item with pin" , "Ornament fastened with a pin" , "Ornament worn fastened to clothing" , "prehistoric tower" .)
