Sunak needing this short article on good argument (6)
I believe the answer is:
growth
'sunak needing this short' is the definition.
The definition and answer can be both related to natural events as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'article on good argument' is the wordplay.
'article' becomes 'th' (I can't justify this - if you can you should give a lot more credence to this answer).
'on' means one lot of letters go next to another.
'good' becomes 'g' (abbreviation).
'argument' becomes 'row' (to row is to argue).
'g'+'row'='grow'
'th' after 'grow' is 'GROWTH'.
Can you help me to learn more?
(Other definitions for growth that I've seen before include "Augmentation" , "Process of development" , "Gradual increase" , "Process of enlargement" , "Development. maturation" .)
