He falls about though able to hold drink (7)
I believe the answer is:
tumbler
This might be a double definition.
'he falls about though able' is the first definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'hold drink' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'to' acts as a link.
Can you help me to learn more?
(Other definitions for tumbler that I've seen before include "Glass for whisky" , "A glass; part of lock" , "A large glass" , "A drop from a bar may occupy this" , "A glass; a pigeon" .)
