Give a dollar - a share of the dole (6)
I believe the answer is:
buckle
'give' is the definition.
(I know that buckle is a more specific form of the action give)
'a dollar a share of the dole' is the wordplay.
'a dollar' becomes 'buck' (slang).
'a share of the dole' becomes 'le' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'buck'+'le'='BUCKLE'
Can you help me to learn more?
(Other definitions for buckle that I've seen before include "Crumple under pressure, like shoe clasp" , "Fasten up - give way" , "Crumple under pressure, or belt fastener" , "(E.g. belt) fastener; crumple" , "It's attached to a belt or shoe" .)
