what is the actual meaning of "would" and "could"? - Lemmy.ca

hii, I am learning English for around 5 years and I still can’t comprehend the meaning of “would” and “count” in some context. are they just past form of “will” and “can”? “would you like coffee” means a person is asking if you liked coffee in past? “I would do it” means I did it in past? I really don’t understand since my language doesn’t have anything like those words.
