I am aving hard times to use the word WOULD AND COULD. Can you explain it in an easy way. Thank you.
Ability – could is the past tense of can. We don’t use would for ability.
She could speak several languages.
They couldn’t dance very well.
Permission - could is a more formal and polite version of using can for permission. We don’t use would for permission.
Could I ask a question please?
Could we go home now?
Instructions and requests - could you and would you are polite ways (more polite than can/will) of telling or asking someone to do something.
Could you write down your name and number please?
Would you lift this for me please?
Could I have my bill please?
Suggestions and advice - could is used for suggestions.
We could meet at Mary’s house this weekend.
You could eat at that new Italian restaurant tonight.
You could try and study more.
Offers and invitations – we also use could to make offers.
I can/could do that for you if you like.
I can/could give you a lift to the station.
Would is more often used for conditionals. See this page http://www.englishpage.com/modals/would.html for general usage guidelines in the conditional, but if you’re still confused about conditionals, I would suggest posting a separate question(s) about conditionals, as they’re a completely different subject.
