Jack's boater? (5)
I believe the answer is:
straw
This clue might be a double definition.
'jack's' is the first definition.
The answer and definition can be both to do with contact as well as being verbs in their base form.
Maybe there's an association between them I don't understand?
'boater?' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for straw that I've seen before include "Dry stalks" , "Pale-yellow - through which one can drink" , "Thatching material" , "Disastrously, it may be the last" , "Stalk of dry grass" .)
