In the Romance, Slavic and Germanic languages and probably many others, verbs conjugate based on the person or thing doing the action, and they don't use helping verbs in the present tense (i.e., you don't say, "I am going", you just say, "I go").

With Spanish there are a couple of standard conjugation schemes for verbs, but I haven't studied it in so long I couldn't tell you what they are.

With the example of "vivir", vivir is the infinitive ("to live"). So generally you use the infinitive with modal verbs ("I liketo live", "She wantsto live").

From there you just need to study some conjugation charts really. Wiktionary is good for providing these https://en.wiktionary.org/wiki/vivir#Conjugation_2.

Vivo = for I ("I live" = "yo vivo")
Vives = you (singular/informal) live.
Vive = she/he/it lives
Vivimos = we live
Vivs = you (plural and/or formal) live
viven = they live

Also I highly recommend checking out Language Transfer on YT - https://www.youtube.com/playlist?list=PLeA5t3dWTWvvwf5fw0Nl7mVk0OUjP1Ln2 for the complete Spanish course, they have a few others. It's all about just listening to a dialogue, pausing when questions are asked, and taking a couple of minutes to think about possible answers (there are often many possible answers). No need to write or read anything, it's just about thinking through things.
