Ordering a taxi when the weather is bad? (7)
I believe the answer is:
hailing
'ordering a taxi' is the definition.
The definition and answer can be both to do with communicating as well as being present participle verbs.
Maybe you can see a link between them that I don't see?
'the weather is bad?' is the wordplay.
'the weather' becomes 'hail' (hail is a kind of weather).
'is bad?' becomes 'ing' (I can't justify this - if you can you should give a lot more credence to this answer).
'hail'+'ing'='HAILING'
'when' acts as a link.
Can you help me to learn more?
(Other definitions for hailing that I've seen before include "Raining ice" , "Greeting" , "Waving to (a taxi)" .)
