Notice stuck on back of car in the Strand (6)
I believe the answer is:
thread
'the strand' is the definition.
(I've seen this before)
'notice stuck on back of car in' is the wordplay.
'notice' becomes 'ad' (short for advert).
'stuck' becomes 'the' (I can't explain this - if you can you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'back of' says to take the final letters.
'in' indicates putting letters inside.
The last letter of 'car' is 'r'.
'ad' put after 'the' is 'thead'.
'thead' enclosing 'r' is 'THREAD'.
Can you help me to learn more?
(Other definitions for thread that I've seen before include "The spiral ridge of a screw" , "Line of cotton - plot (of book, film)" , "Thin yarn" , "Twine" , "Hatred (anag)" .)
