is inashindwa also corrrect or is there a nuance?
"Timu yao inashindwa kila mechi" should be accepted. "Timu yao hushindwa kila mechi" might also be considered correct, but that is a different issue.
'inashindwa' is still not accepted as correct. Reported 01.04.2020
In sports terms ku-funga and ku-shinda both mean 'to win'. Staying with sports, ku-funga can also mean 'to score'.
