Business to begin -- right for any number to get involved (8)
I believe the answer is:
commerce
'business' is the definition.
(I've seen this before)
'begin right for any number to get involved' is the wordplay.
I cannot quite see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is located in the answer.
'number' could be 'm' (M is an example) and 'm' is present in the answer.
'get' could be 'come' (synonyms) and 'come' is found within the remaining letters.
This may be the basis of clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for commerce that I've seen before include "Activity of buying and selling" , "Business, industry, trade" , "Trading exchanges" , "The buying and selling of goods and services" , "Sales and purchases of goods and services" .)
