1= si, la veo.
2= no, no la veo.
3= si, la veo.
4= si, la veo.
Using the model/example, if you see “si” then that means yes. Add the la and you’ll get “Si, la veo.” which means “Yes, I see it.” If you see “No, no” then you’d still add the la. “No, no la veo.” means “No, I don’t see it.”
SEPARATE WORD MEANINGS
Si= Yes
No= No
Veo= I see
La= The/it
