Bore given heads-up about energy tariff (9)
I believe the answer is:
tolerated
'bore' is the definition.
('tolerate' can be a synonym of 'bear')
'given heads-up about energy tariff' is the wordplay.
'given heads up' becomes 'told' (I can't justify this - if you can you should believe this answer much more).
'about' indicates putting letters inside.
'energy' becomes 'e' (physics symbol as in E=mco).
'tariff' becomes 'rate' (I've seen this before).
'e'+'rate'='erate'
'told' placed around 'erate' is 'TOLERATED'.
Can you help me to learn more?
(Other definitions for tolerated that I've seen before include "Borne" , "Bore" , "accepted?" , "Endured; allowed" , "Countenanced" .)
