Support the breaking of a lease (5)
I believe the answer is:
easel
'support the breaking' is the definition.
'easel' can be an answer for 'support' (I've seen this in another clue). I'm unsure of the 'the breaking' bit.
'of a lease' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'lease' anagrammed gives 'EASEL'.
Can you help me to learn more?
(Other definitions for easel that I've seen before include "artistic aid" , "Artist's support frame" , "Painting support" , "Artist's equipment" , "artist's requisite" .)
