Questions & Answers about Lleno la botella con agua fría.

Why is the verb llenar conjugated as lleno?

We use the present indicative first-person singular for yo (I). The stem is llen- and the -o ending signals yo, so lleno literally means “I fill.”

Why don’t we say yo lleno la botella con agua fría?

Spanish usually drops the subject pronoun when the verb ending already makes it clear. The -o in lleno tells you the subject is yo, so yo is optional (and often omitted).

Why do we use the article la before botella?

Botella is a feminine, singular noun. The definite article la matches its gender and number, giving la botella (“the bottle”).

Why do we use con to introduce agua fría? Could we also use de?

To fill something, you can say llenar algo con algo, using con to express “with.” Yes, you can also use de: Lleno la botella de agua fría is equally correct. Both patterns mean “I fill the bottle with cold water.”
