How to use it
El cansancio (noun, masculine, from the verb cansar/cansarse) means 'tiredness' or 'fatigue'. Common collocations: sentir cansancio, el cansancio acumulado, caer rendido de cansancio. It's more general than fatiga, which often carries a more clinical or intense connotation.
Common mistake
Cansancio (everyday tiredness) is milder than fatiga, which is often used in more clinical or intense contexts (fatiga crónica, chronic fatigue) — the two overlap but are not perfect synonyms.
