Lesson 2. Nasal vowels and diphthongs

I can hear and read a nasal sound as ONE sound, not as “vowel plus n”, understand why a word has an m or n you can't hear, and read any Portuguese diphthong aloud in one syllable, without splitting it in two.

A nasal sound is one sound, not two

The tilde, and m and n at the end of a syllable

The tilde ~ makes a vowel nasal: the air goes through the mouth and the nose at once, but it's still ONE sound. English has no nasal vowels and tends to add an n: o pão is not “PAWN”, and not “POW” either. The letters m and n at the end of a syllable do the same job. In sim, o fim, bem, o homem, o som the m isn't pronounced as m: it shows that the vowel is nasal. That gives the full set: am, em, im, om, um. Nasal diphthongs are two nasal sounds in one syllable: ão (não, o cão), ãe (os pães), õe (as lições). Final em ends in a short y, as in “yes”: bem, a viagem, o homem. How to practice it. A nasal sound can't be checked in writing: the checker ignores the tilde and accepts “pao” for “pão”. So we listen to nasal sounds and choose, and we write them only where the letters differ. Common mistakes: • NOT “PAWN” or “POW” — o pão is one nasal sound, not a vowel plus n. • NOT “SIM” with an m — in sim the m isn't pronounced. • NOT “BEM” with an m — bem ends in a nasal sound with a short y. • NOT “HOH-mem” — in o homem the h is silent, and the m only makes the vowel nasal.
A nasal sound is one sound, not two

The letters m and n at the end of a syllable aren't consonants here: they mark a nasal vowel.

The tilde, and m and n at the end of a syllable
The tilde ~ makes a vowel nasal: the air goes through the mouth and the nose at once, but it's still ONE sound.

Two vowel letters, one syllable
Two vowels in one syllable are run together: ei — a ideia, ou — o ouro, ai — a praia, au — a aula, eu — o museu, oi — a coisa. The pair ou is one closed o: in o ouro you hardly hear a second sound. The pair eu is “eh-oo” in one syllable: o museu. The pair ei sounds close to English “ay”, but in Lisbon it starts lower, from “uh”, and the y after it is very short: a ideia. Final ão and am sound the same but are spelled differently. am is a verb ending (falam, “they speak”; the verb forms come in module 2), and ão ends nouns like o pão and o cão. The checker ignores the tilde but sees the letters ão and am: mix them up, and the answer is marked wrong. One more warning: a lição and a canção have the letter ç, and in o museu and a coisa the letter s stands between vowels and sounds like z in “zoo”. Both rules come in lesson 3. Common mistakes: • NOT “OH-oo-roh” with two vowels — o ouro has one closed o. • NOT “MYOO-zee-um” — o museu ends in “eh-oo”, in one syllable. • NOT “ah-OO-lah” in three syllables — in a aula the first two letters make one syllable. • NOT “falão” — “they speak” is spelled falam, with m.
