A woman could ride in one (5)
I believe the answer is:
habit
This clue might be a double definition.
'a woman' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'ride in one' is the second definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'could' acts as a link.
Can you help me to learn more?
(Other definitions for habit that I've seen before include "Custom, wont" , "Regular practice" , "Custom or monk's robe" , "Dress - custom - practice" , "Custom; riding dress" .)
