Frequently Asked Questions
So if I say 'Soy cansado,' is it always wrong?
It's not grammatically wrong, but it's probably not what you mean. It means 'I am a tiring person.' It's a very negative self-assessment! 99% of the time, when you want to talk about your own tiredness, you will use 'Estoy cansado/a'.
Can I say 'estoy cansado de mi trabajo'?
Yes, absolutely! This is a very common phrase. 'Ser cansado' describes the job itself ('El trabajo es cansado'). 'Estar cansado de...' describes your emotional state about it ('Estoy cansado de mi trabajo' - I'm tired/sick of my job).
Does this ser/estar rule apply to other adjectives?
Yes! This is a key concept in Spanish. The same pattern works for many adjectives, most famously 'aburrido'. 'Ser aburrido' means 'to be boring', while 'estar aburrido' means 'to feel bored'. Mastering this pattern will make your Spanish sound much more natural.
