tl;dr Spanish Irregular Commands Positive tú

[@alexiagutierrez-2098]

No es saber, es ser! Saber=sabe

[@bayardnielsen8198]

"Ve" is the irregular tú command form of "ir" and the regular tú command form of "ver". As Alexia points out below --> Sé is the irregular tú command of "ser," not saber. :-)
