The weather is changing so wrap up (7)
I believe the answer is:
wreathe
'wrap up' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Maybe they are linked in a way I don't understand?
'the weather is changing' is the wordplay.
'is changing' indicates an anagram.
'weather' with letters rearranged gives 'WREATHE'.
'so' acts as a link.
Can you help me to learn more?
(Other definitions for wreathe that I've seen before include "Surround, encircle" , "wind" , "Encircle with flowers" , "(E.g smoke) curl" , "Weather (anag.)" .)
