Questions & Answers about Estoy cansado, pero quiero estudiar igualmente.

Why is it estoy cansado and not soy cansado?

Spanish uses estar for temporary states and conditions, and ser for more permanent or defining characteristics.

• Estoy cansado = I am tired (right now / at the moment / these days) → a temporary condition.
• Soy cansado is usually wrong if you just mean you’re tired. It could work in a very specific, unusual sense like I’m a tiring person / I’m the kind of person who gets tired easily, but that’s rare and context‑dependent.

So for physical or mental tiredness, you normally say estar cansado.

Why cansado and not cansada? How does this change?

Cansado agrees in gender and number with the person it refers to.

• A man: Estoy cansado.
• A woman: Estoy cansada.
• A group of men / mixed group: Estamos cansados.
• A group of women: Estamos cansadas.

So if you are female and speaking about yourself, you would say Estoy cansada, pero quiero estudiar igualmente.
