The diminutive is one of the first things you notice about spoken Brazilian Portuguese: cafezinho, rapidinho, só um minutinho. Morphologically it is simple — you add a suffix, usually -inho (masculine) or -inha (feminine). The two things worth getting right are which suffix variant to use (-inho vs -zinho) and the small spelling adjustments that keep the original sound intact. This page covers the formation. For what diminutives mean socially — affection, softening, downplaying — see the pragmatics page on diminutives.
The default: -inho / -inha
For most words, drop the final unstressed vowel and add -inho or -inha, matching the gender of the base word.
| Base | Diminutive | English |
|---|---|---|
| gato | gatinho | little cat / kitty |
| casa | casinha | little house |
| livro | livrinho | little book |
| bonito | bonitinho | cute |
Que gatinho lindo! De quem é?
What a cute little cat! Whose is it?
Eles compraram uma casinha na praia.
They bought a little house at the beach.
When to use -zinho / -zinha
Use the longer variant -zinho/-zinha (with the linking z) when the base word ends in:
- a stressed vowel: café → cafezinho, avó → avozinha, pé → pezinho
- a nasal sound (~, -m, -n): pão → pãozinho, mão → mãozinha, irmã → irmãzinha, homem → homenzinho
- a consonant like -r, -l, -s, -z: flor → florzinha, amor → amorzinho, animal → animalzinho, colher → colherzinha
Vamos tomar um cafezinho depois do almoço?
Shall we have a little coffee after lunch?
O cheiro de pãozinho quentinho de manhã é tudo.
The smell of warm little bread rolls in the morning is everything.
Dá a mãozinha pra mim atravessar a rua.
Give me your little hand to cross the street.
Tinha uma florzinha amarela crescendo na calçada.
There was a little yellow flower growing on the sidewalk.
Why two variants exist
The -zinho form preserves the integrity of the base word. If you tried to attach plain -inho to café, you'd either crush the stressed final vowel or create an awkward sequence; the linking z lets the base stay recognizable and keeps its stress. So the rule is really about protecting the base word's sound: when the word ends in something that can't gracefully swallow -inho, Portuguese inserts the z.
Spelling changes that protect the sound
Portuguese spelling encodes pronunciation, so when adding -inho would change how a consonant sounds, the spelling adjusts to keep the original sound.
| Base | Diminutive | What's protected |
|---|---|---|
| amigo | amiguinho | hard /g/ — add u so it isn't read as /ʒ/ |
| fogo | foguinho | hard /g/ kept with u |
| chico / pouco | chiquinho / pouquinho | hard /k/ — write qu |
| peixe | peixinho | final -e drops; /ʃ/ kept |
| nariz | narizinho | -z base takes -inho directly |
O amiguinho do meu filho dorme aqui hoje.
My son's little friend is sleeping over today.
Espera só um pouquinho, já estou indo.
Wait just a little bit, I'm coming.
O peixinho do aquário morreu, que tristeza.
The little fish in the aquarium died, how sad.
Without the u, amigo → amiginho would be read with a soft /ʒ/ ("amizhinho"); the u in amiguinho keeps the hard /g/. The same logic gives pouquinho and chiquinho (the qu preserves the hard /k/).
Pluralizing diminutives
For plain -inho/-inha, just add -s: gatinho → gatinhos, casinha → casinhas.
The -zinho/-zinha forms show double pluralization — both the base word and the suffix go plural. You pluralize the original noun, then attach -zinhos/-zinhas:
| Base | Plural of base | Diminutive plural |
|---|---|---|
| pão | pães | pãezinhos |
| flor | flores | florezinhas |
| animal | animais | animaizinhos |
| colher | colheres | colherezinhas |
| papel | papéis | papeizinhos |
Comprei uns pãezinhos pro café da manhã.
I bought some little bread rolls for breakfast.
Os animaizinhos do sítio acordam com o sol.
The little farm animals wake up with the sun.
Other diminutive suffixes
-inho dominates, but Portuguese has a few others, mostly lexicalized or stylistic:
- -ico/-ica: burro → burrico (donkey), namoro → namorico (a little fling). Often slightly literary or fixed.
- -eto/-eta, -ote: globo → globeto, velho → velhote (a little old man). More marginal.
- -zito/-zita: café → cafezito — heard but far less common in BR than cafezinho.
These are not freely productive the way -inho is; learn them as part of specific words rather than as a rule.
A note for English speakers
English has almost no productive diminutive. It uses little (a little house) or a handful of frozen suffixes (-y/-ie in doggy, kitty, -let in booklet). Portuguese instead inflects the word itself, and does so constantly. Two consequences: (1) don't translate every -inho with "little" — um cafezinho is just "a coffee" in tone, not "a small coffee"; the suffix often signals warmth, not size; (2) the diminutive attaches to far more than nouns — adjectives (bonitinho), adverbs (rapidinho, agorinha), even some interjections (tchauzinho). For these meaning-and-tone effects, see the pragmatics page.
Common Mistakes
❌ Vamos tomar um cafeinho?
Incorrect — 'café' ends in a stressed vowel, so it needs -zinho.
✅ Vamos tomar um cafezinho?
Shall we have a little coffee?
❌ O amiginho do meu filho.
Incorrect — without the 'u' the g reads as /ʒ/.
✅ O amiguinho do meu filho.
My son's little friend.
❌ Comprei uns pãozinhos.
Incorrect — the base must pluralize too: pão → pães.
✅ Comprei uns pãezinhos.
I bought some little bread rolls.
❌ Espera um poucinho.
Incorrect — the hard /k/ needs 'qu': pouquinho.
✅ Espera um pouquinho.
Wait a little bit.
❌ Que casinho linda!
Incorrect — 'casa' is feminine, so the suffix is -inha.
✅ Que casinha linda!
What a lovely little house!
Key Takeaways
- Default suffix: -inho/-inha, matching the base word's gender (gatinho, casinha).
- Use -zinho/-zinha after a stressed vowel, nasal, or consonant (cafezinho, pãozinho, mãozinha, florzinha).
- Spelling protects the sound: amigo → amiguinho (keeps hard /g/), pouco → pouquinho (keeps hard /k/).
- Double pluralization with -zinho: pluralize the base first — pães → pãezinhos, animais → animaizinhos.
