Let's learn three more "first-typers".

duoti - to give
kalbėti - to speak, to talk
gyventi - to live

Remember that you must pay strict attention to the 3rd person (jis, ji, jie, jos) of all verbs.

jis, ji, jie, jos duoda (he, she, they give)
jis, ji, jie, jos kalba (he, she, they speak)
jis, ji, jie, jos gyvena (he, she, they live)

The stems of these verbs are duod, kalb and gyven. Can you make all the other persons out of them?

duod + u = duodu (I give)
duod + i = duodi (you give)
duod + a = duoda (he, she, they give)
duod + ame = duodame (we give)
duod + ate = duodate (you give)

kalb + u = kalbu (I speak)
kalb + i = kalbi (you speak)
kalb + a = kalba (he, she, they speak)
kalb + ame = kalbame (we speak)
kalb + ate = kalbate (you speak)

gyven + u = gyvenu (I live)
gyven + i = gyveni (you live)
gyven + a = gyvena (he, she, they live)
gyven + ame = gyvename (we live)
gyven + ate = gyvenate (you live)
