Sé vs Sabe

Sé vs Sabe
 

Yo también sé poco por esa razón.
Yo también sabe poco por esa razón. I also know???? sabe = you Is "sabe" here not the verb saber.

También sé poco por esa razón.
También sabe poco por esa razón.

I also know little for that reason.
I also know little for that reason.
I also know little for that reason.
He also knows little for that reason.

The first person conjugation of saber is 'sé'.
"Sabe" is the third person conjugation of saber.

The second sentence you wrote isn't grammatically correct.

The third and fourth sentences are grammatically sound.
(However, a person hearing the fourth sentence, said without a subject pronoun, would need to know or be able to deduce who the subject is.)

The verb saber can be translated as 'know', 'find out', 'hear', or 'learn', depending on the context. If it's followed by a preposition, it can have other meanings.

'Saber a' means 'tastes like'. Sabe a chocolate. (It tastes like chocolate.)

Gracias.
