According to number of syllables, words fall into monosyllables, disyllables, trisyllables and polysyllables. So you can remember, the syllable is a phoneme or group of phonemes pronounced through only a sound emission. It is important to highlight that the basis of syllables in Portuguese are the vowels.
Let's see how words are classified according to the number of syllables they have:
→ MONOSYLLABAS
monosyllables are the words formed by a single syllable. See some examples:
flower
sea
there is
who
how
only
already
nor
what
→ DISYLLABLES
Dissyllables are the words formed by two syllables. See some examples:
there: there
duty: duty
solder: solder
flavor: flavor
love love
You you
colors: colors
hint: hint
→ TRISYLLABAS
Trisyllables are the words formed by three syllables. See some examples:
layer: bed
attract: a-tra-ir
January: January
beauty: be-le-za
planet: planet
pepper: pi-men-ta
butcher shop: butcher shop
salad: sa-la-da
→ POLYSYLLABLES
polysyllables are the words formed by more than three syllables. See some examples:
butterfly: bor-bo-le-ta
Mariana: Ma-ri-a-na
Goiatuba: Goi-a-tu-ba
brazilian: brazilian
aristocracy: a-ris-to-cra-ci-a
festivity: fes-ti-vi-da-de
shelf: pra-te-lei-ra
See how simple it is to study the classification of words in terms of the number of syllables? Now, we suggest that you also study about the digraphs and of the vowel encounters. Good studies!
