I need to learn Spanish for work. But I can't figure out the verbs. I get them mixed up. Can you tell me if anyone knows any websites where it's well explained in detail.

If you don't want to hire a tutor, then you have to do the study yourself by searching for special websites. You can try looking at gustar activities worksheets here But I still think that such sites exist only for support, not for complete language learning.

There is no possibility of hiring a tutor yet. So I'm trying to learn everything on my own. Thank you for the website.

You can try one of these websites, and perhaps use Duolingo for extra practice. Good luck!
