Common mistakes to avoid
1. If I would have money ❌
Do not use would after if. In the if part, use the Past Simple. Would goes in the other part: If I had money, I would travel. The present is wrong too: If I have money, I would travel ❌.
2. I would to swear ❌
After would, use the base form, with no to and no -s: I would swear, she would swear. This is true for all modal verbs (helper verbs like can, could, should and must). But remember I would like to swear: here, to belongs to like.
3. I would can swear ❌
Would cannot go with can or must. Use could instead of “would can”: I could swear. Use would have to instead of “would must”: I would have to swear.
