mas (porém) × mais (quantidade); mal (adv., ↔ bem) × mau (adj., ↔ bom); a (prep./art.) × há (haver); senão × se não; por que / porque / por quê / porquê; afim × a fim de; onde × aonde
Explanation
Several Portuguese words sound alike or look alike but have different meanings and spellings, and getting them wrong is one of the most common writing mistakes. Learn the high-value pairs first: 'mas' (but) vs 'mais' (more); 'mal' (adverb, the opposite of 'bem' — both have an L) vs 'mau' (adjective, the opposite of 'bom' — both are adjectives); 'a' (a preposition or article) vs 'há' (the verb 'haver', meaning 'there is' or 'ago'). Then come 'senão' (otherwise/except) vs 'se não' (if not), and above all the four porquês: 'por que' (why, in a question, two words), 'porque' (because, one word), 'por quê' (why, at the end of a sentence, accented) and 'porquê' (the noun 'the reason', used with an article). Add 'afim' (having affinity) vs 'a fim de' (in order to / keen on someone), and 'onde' (where) vs 'aonde' (to where, with verbs of motion). If you speak Spanish, the same traps exist ('mas/más', 'sino/si no', 'porque/por qué/porqué'), which helps a lot — but watch out for 'há' from 'haver', where Spanish uses 'hace' or 'hay'.
Examples
Note
Memory tricks: 'mal' pairs with 'bem' (both have an L); 'mau' pairs with 'bom' (both are adjectives). For the porquês: a question uses 'por que' (separated), an answer uses 'porque' (joined); at the end of a sentence it takes the accent ('por quê?'), and with an article it becomes the noun 'o porquê'.
