Chaminé É Oxítona Paroxítona Ou Proparoxítona

Regra prática de acentuação para palavras como chaminé

A gente precisa parar de confundir as coisas. Tem um monte de gente que olha para "chaminé" e já parte direto para "proparoxítona" só porque a palavra parece grande ou terminada em ditongo. Nada disso. A regra é simples e quem não domina isso acaba errando até na hora de acentuar palavras que não dão trabalho.

chaminé é oxítona paroxítona ou propropoxítona

Chaminé é oxítona. A sílaba tônica é a última: chi-ma-NÉ. Palavra oxítona terminada em -é (e aberto) recebe acento agudo. Fim da história. O mesmo vale para outras palavras do tipo: xícara, café, cipó, herói. Todas oxítonas tônicas no final. A confusão acontece porque muitas pessoas associamWords ending in -e, -o, -em, -ens, -ã, -ões automaticamente to proparoxítona, but that's simply not true. Most words ending in those letters are actually paroxytonic (like "célula," "médico," "fármaco"), but oxytone words like "chaminé," "café," and "travesti" are the exceptions that follow the last-syllable stress rule instead.

I once had someone come to me with a full list of twenty words, asking if they were all proparoxytone because they ended in -e. The answer was no. Only two were, and those were the ones carrying the accent. The rest were oxytone. The only real way to sort this out is to say each word out loud and listen for where the stress naturally falls. When you do that with "chaminé," your mouth closes on the last syllable and it carries more weight. That's your tell. Another thing people mess up constantly: words ending in -ei or -oi. Oxítona with diphthong gets the accent too. "Chapéu," "avô," "herói." Proparoxytone is reserved almost entirely for words where the stress lands on the third-from-last syllable and you don't have any special ending rules overriding it. Something like " lâmpada," "mágico," "público." If you're saying it and the strong beat isn't on the last syllable or the antepenultimate, stop second-guessing yourself and just count syllables.

The bigger problem though is that even if you know the rule, typing fast makes you forget. I used to miss accents on "cafeína" versus "café" all the time because my fingers assumed they'd sound the same. Now I just run through a quick check every time I type anything with an open vowel at the end of an oxytone. Takes two seconds. Saves a lot of embarrassment in formal writing. If you want to test yourself quickly, here's what I do. Take any word, say it out loud, mark the stressed syllable, then look at the ending. If the stress is on the last syllable and it ends in a, e, o (open), em, ens, it needs an accent. If it's on the antepenultimate and doesn't end in the prohibited oxytone patterns, it's proparoxytone and also gets an accent. Everything else is paroxytone and gets one only if it ends in n, l, r, x, ps, ã, ãs, ditongo.
