Question

When you do a conjugated verb:
When I say Cantar (sing) and I put Yo (I) in front of it. Does it become (Yo canto) OR (Canto) ??

Answer 1

Yo canto and canto are both fine.
The conjugated verbs in Spanish have implicit the pronounin all tenses.
If you are fluent in Spanish you don't use the pronouns always , because each pronoun has its verbal form. The people that speak Spanish understand the action without the pronoun if you say canto.
Cantar present indicative.
Yo canto
Tu cantas
El/ella canta
Nosotros cantamos
Vosotros cantais
Ellos cantan.
