Introduction
Many English speakers learning Brazilian Portuguese struggle with similar-looking words that sound different. Ontem and jovem are two such words: they both end in -em but have distinct pronunciations and common learner mistakes. This article explains why, gives clear pronunciation rules, practical tips, and short drills to help you sound more natural in everyday situations.
Why Ontem and Jovem Confuse Learners
Both ontem and jovem end with the letters em, which in Brazilian Portuguese represent a nasal vowel or a nasal diphthong depending on context. English does not have the same nasal vowel system, so learners often apply English patterns and produce non-native sounds. Additionally, stress patterns and the behavior of the letter j differ from English expectations, creating more errors.
Key pronunciation differences at a glance
Ontem: pronounced with an initial nasal vowel sound and a final unstressed nasal syllable, often close to [ˈõ.teɪ̃] or [ˈõ.tẽj] depending on accent and speech speed.
Jovem: pronounced with a non-nasal first vowel and a nasalized final syllable, typically [ˈʒo.vẽj] or [ˈʒo.vẽ̃].
Pronunciation rules you need to know
Rule 1 — Nasal vowels with -em: In Brazilian Portuguese, -em at the end of words commonly nasalizes the preceding vowel. The result is not a consonant-plus-nasal like English ng, but a nasalized vowel with a subtle glide in careful speech.
Rule 2 — Syllable stress: Ontem and jovem are both two-syllable words with stress on the first syllable. This means the first vowel should be clearer and slightly stronger than the final nasal syllable.
Rule 3 — The letter j: In Brazilian Portuguese, j is pronounced like the s in measure or the zh sound [ʒ]. It never becomes the English y sound in these words.
Phonetic breakdown and practical cues
Ontem: break into syllables on-te(m). First syllable on is nasalized. Pronounce on as a nasal mid-back vowel like Portuguese õ. Say the second syllable vaguely like te with nasalization at the end so you get on-tem with on emphasized. Practice: Ontem = ON-tem (nasal ON).
Jovem: break into syllables jo-vem. First syllable jo is like the English joe but shorter, with the j as [ʒ]. The second syllable vem is a nasalized e: pronounce ve as veh with a nasal ending. Practice: Jovem = ZHO-vene nasalized at the end.
Common pronunciation mistakes and how to fix them
Mistake 1 — Adding a consonant: Learners often add an extra n or m sound at the end, saying on-tem as on-temn or jo-vem as jo-vemn. Fix: Stop trying to pronounce an explicit n or m at the end. Focus on nasalizing the vowel instead. Practice humming the vowel while closing your mouth slightly; do not add a hard n or m consonant.
Mistake 2 — Using English j or y sound: Saying jovem as yo-vem with a y sound. Fix: Practice the [ʒ] sound. Put your tongue low and center, let the air pass over the tongue while vibrating the vocal cords. Use minimal pairs: jovem [ʒo.vẽj] vs iogurte [jo.gur.tʃi] (note different y-like patterns) to feel the contrast.
Mistake 3 — Wrong vowel quality: Pronouncing ontem as on-TEHM with a strong e in the second syllable that is not nasalized. Fix: Keep the second syllable lighter and nasal. Think of it as te+h% nasalized rather than a full clear e. Record yourself and compare to native audio, focusing on the nasal color, not on vowel height.
How to produce nasal vowels correctly
Step 1: Say the vowel alone, for example e as in set but a bit more closed for Portuguese e. Step 2: Open your nasal passages by exhaling through the nose slightly while holding the vowel. You should feel a buzzing in your nose. Step 3: Shorten the vowel; the nasalized vowel is usually shorter and less stressed. Practice with em: e + nasal airflow = ẽ.
Sound exercise: Repeat em, ẽ, ẽm (without a pronounced m), listening for nasal resonance. Use a mirror or place a hand lightly on your nose to feel vibration. Avoid closing the lips as if to add an m consonant.
Practical pronunciation drills and short phrases
Beginner drill 1 — Isolated words: Repeat slowly: Ontem
Jovem
Homem (for contrast)
Alguém (see similarity with -em)
Beginner drill 2 — Minimal pairs to highlight contrast: Ontem vs Outem (nonexistent but useful for practice), Jovem vs Joel (different j behavior), Vem vs Vento (vem nasal, vento non-nasal). Say each pair slowly, then at normal speed.
Scene-based practice — Travel: Ontem eu fui ao mercado. Pronunciation practice: Ontem eu fui ao mercado. Break: ON-tem eu fui ao mer-CA-do. Focus on ON nasal, TEM light nasal.
Scene-based practice — Social: O jovem pediu água. Pronunciation practice: O jovem pediu água. Break: O ZHO-ven pe-DIU Á-gua. Emphasize ZHO at the start and the nasal end on vem.
Restaurant practice: Ontem eu comi peixe. Pronunciation practice: Ontem eu comi peixe. Break and repeat slowly, then in normal speech. Travel tip: Speakers often reduce vowels in casual speech; keep the nasal hint even when speaking fast.
Classroom exercises and teacher prompts
Exercise 1 — Shadowing: Find a short audio clip of a Brazilian speaker using ontem and jovem. Play one sentence and immediately repeat, matching nasal quality and stress. Do this ten times for each word.
Exercise 2 — Record and compare: Record yourself saying Ontem eu estive lá and O jovem estuda aqui. Compare waveform or just listen back. Mark where you hear strong consonant endings and reduce them to a nasal vowel.
Exercise 3 — Partner drill: One student says a phrase containing ontem or jovem; the partner guesses the word while listening only to the last syllable. This trains the ear to hear nasal vowels rather than consonant endings.
Everyday practice tips for fast improvement
Tip 1 — Use minimal sentences you will say in real life: Hoje, ontem, amanhã; O jovem trabalha aqui; Ele perguntou ontem. Repetition in real contexts builds muscle memory.
Tip 2 — Focus on nasal resonance, not on adding m or n: Hold a short nasal hum before ending the word. Say ooooo~ then release into the next word without a hard consonant.
Tip 3 — Learn a few related words with -em to generalize the pattern: alguém, ninguém, também, porém. Compare them with jovem and ontem to get used to variations of nasalization.
Short practice list for daily drills
Ontem eu fui ao cinema.
O jovem é estudante.
Alguém está na cozinha.
Ninguém sabe a resposta.
Ele veio ontem de manhã.
Common learner questions answered
Question 1 — Should I always nasalize -em endings? Generally yes at the end of a word or before a consonant that allows nasalization. However, speech rate and regional variation change the exact quality. For beginners, aim for consistent nasalization to be understood.
Question 2 — Is jovem pronounced with a strong j like in judge? No. The j in jovem is voiced postalveolar fricative [ʒ], similar to the s in measure, not the affricate ch or the English j in judge.
Question 3 — Will native speakers correct me? Many will still understand non-native pronunciations, but improving nasal vowels and avoiding added consonants will make your Portuguese sound more natural and easier to follow in fast speech.
Additional resources and listening practice
Resource 1 — Brazilian podcasts for learners: Choose short episodes that include everyday conversations and listen for -em endings. Pause and repeat sentences containing ontem and jovem.
Resource 2 — Pronunciation apps: Use an app that shows waveforms or IPA feedback so you can compare nasal vowel length and quality. Target apps that highlight nasalization features.
Resource 3 — Language exchange: Ask partners to say sentences slowly and mark nasal endings for you. Swap roles: you say a sentence and they tell you whether your final syllable sounded nasal enough.
Conclusion
Ontem and jovem seem similar on paper but differ in vowel quality, nasalization, and the j sound. Mastering nasal vowels, avoiding added consonants at the end, and practicing stress and rhythm will make your speech sound more natural. Use short real-life sentences, shadow native audio, and focus on nasal resonance to improve quickly.
