Sign that lawyer is into pastries (6)
I believe the answer is:
pisces
'sign' is the definition.
(I know that Pisces is a sign)
'lawyer is into pastries' is the wordplay.
'lawyer' becomes 'sc' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'is into' is an insertion indicator.
'pastries' becomes 'pies' (pie is a kind of pastry).
'sc' put into 'pies' is 'PISCES'.
'that' is the link.
Can you help me to learn more?
(Other definitions for pisces that I've seen before include "Twelfth zodiacal sign" , "Fish star sign" , "Twelfth sign of the zodiac, the Fish" , "Spice for the Fish" , "stars" .)
