Key Differences
"Could" is the past tense of "can" and is used to indicate ability or possibility in the past, such as "I could swim when I was young." "Would" is the past tense of "will" and is used for hypothetical situations or future intentions seen from the past, like "I would travel more if I had the time."

"Could" also expresses a theoretical possibility or potential ability in the present or future, such as "You could try calling her." In contrast, "would" often refers to a repeated action in the past, similar to "used to," as in "When we were kids, we would play outside for hours."

In conditional sentences, "could" is used in the subordinate clause to suggest a possible outcome, like "If I had time, I could learn Spanish." "Would" in conditional sentences indicates the likely outcome of a hypothetical situation, as in "If I won the lottery, I would buy a house."
