Correct use of Would
‘Would’ is used to mean courtesy and casual habits
I would swim.
- I mean I used to swim but now I don’t. It’s an irregular habit that I used to do but I don’t do anymore. In these cases, we should use ‘would’.
He would smoke.
Would you please lend me some money?
– Using would in a sentence brings a Politeness. Here we could use ‘can’.
Can you please lend me some money?
But can means to be able to do something.
Such as –
- I can sing.
- I can play football.
# So, in my opinion it is better not to use can in all these cases.
