What is a phrase meaning ‘to prepare for all possibilities’?
A good day to you too, Inese Ozolina.
A phrase that we can use that means to prepare for all possibilities could be ‘just in case’. It can be used to imply the possibility of something to happen.
For instance, we can say, “It would be better to bring some cash just in case they don’t accept card payments in the countryside.”
This means that it will be better to be prepared because there is a possibility that stores in the countryside don’t accept card payments.
