Accommodating description of race-track at times (9)
I believe the answer is:
easygoing
'race-track at times' is the definition.
I can't judge whether this defines the answer.
'accommodating description' is the wordplay.
'accommodating' becomes 'easy' (I've seen this in another clue).
'description' becomes 'going' (I can't justify this - if you can you should give a lot more credence to this answer).
'easy'+'going'='EASYGOING'
'of' is the link.
Can you help me to learn more?
(Other definitions for easygoing that I've seen before include "relaxed" , "Calm" .)
