At certain points, a crooked deal seems heavy to bear (6)
I believe the answer is:
leaden
'heavy to bear' is the definition.
I can't tell whether this definition defines the answer.
'at certain points a crooked deal' is the wordplay.
'at' means one lot of letters go next to another.
'certain points' becomes 'en' (two compass points. I am not sure about the 'certain' bit.).
'a crooked' is an anagram indicator (a crooked or disrupted version of the letters).
'deal' with letters rearranged gives 'lead'.
'en' after 'lead' is 'LEADEN'.
'seems' is the link.
Can you help me to learn more?
(Other definitions for leaden that I've seen before include "Slow-moving, being like heavy metal" , "Heavy or slow, like dark-gray metal" , "Heavy - overcast" , "Gloomy - slow-moving" , "Heavy - plodding" .)
