Obstruct and deal with lifting mechanism (5,3,6)
I believe the answer is:
block and tackle
'mechanism' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'obstruct and deal with lifting' is the wordplay.
'obstruct' becomes 'block' (synonyms).
'deal with' becomes 'tackle' (I've seen this before).
'lifting' is a charade indicator (letters next to each other).
'block'+'and'+'tackle'='BLOCK AND TACKLE'
Can you help me to learn more?
(Other definitions for block and tackle that I've seen before include "Lifting gear" , "How sportsmen defend" , "Rugby moves" , "weightlifter" , "lifting equipment" .)
