How to Say "weary" in Spanish
The Spanish word for “weary” is “cansado” — A1 level. This is a very common word in everyday Spanish.

Examples

¿Estás cansada, María? Te ves agotada.
Are you tired, Maria? You look exhausted.

State of Being (Estar)
Since being tired is a temporary condition or state, you must always use the verb 'estar' (to be) with 'cansado' (e.g., 'Estoy cansado').
Match the Person
Like most Spanish descriptive words, 'cansado' must match the gender and number of the person or thing it describes: 'cansada' (feminine singular), 'cansados' (masculine plural), 'cansadas' (feminine plural).
Using the Wrong 'To Be' Verb
Mistake: “Soy cansado.”
Correction: Estoy cansado. Using 'ser' (Soy) implies being tired is a permanent characteristic, which isn't usually true.
