Yuri's Spanish Study CardBasic

The Spanish card displays 38 independent tables with the most important grammar elements. Los Pronombres Personales De Sujeto (Subject Personal Pronouns) determine the three main colours used throughout the card.
They are the persons who the sentence refers to. In English they are the words I, you, he, she, it, we, you and they. The singular personal pronouns (I, you, he, she, it), are represented in a light shade of yellow, purple and green. And the plural pronouns (we, you, they), are represented in a dark shade.
Usted means you in English, but it’s the formal way to address someone. It’s in the group of green colours, because it’s conjugated like the third person él and ella.
Ustedes means you (plural) in English. Ustedes is the formal way of vosotros, vosotras. It’s in the group of green dark colours, because it’s conjugated like the third person plural ellos and ellas.
