Can You name 20 Infinitives in spanish?

In english they translate to "to swim" or "to speak." So in spanish the Word you would use to say "to swim" would be "nadar." In a sense, they are the native form of the verb, un-conjugated. So you use this form with the -ar at the end (some verbs have er at the end) when you're going to say "I need to swim." So, you would say, "Necesito a Nadar." Good luck!
