The Plural of Portuguese Words Ending In L

Portuguese nouns and adjectives ending in the letter l form the plural according to a small set of regular patterns. The key factor is the vowel that precedes the final consonant.

For this reason, these words can be grouped into five subcategories: -al, -el, -ol, -ul, and -il. The -il subcategory is more nuanced and requires closer attention.

Words ending in -al

Words ending in -al form the plural by dropping the final l and adding -is.

animal → animais (animal → animals)

This rule is consistent and applies to the vast majority of words in this subgroup.

Words ending in -el

Words ending in -el follow the same structural rule: the final l disappears and -is is added. Accent placement, however, depends on stress.

When the word is stressed on the final syllable, the plural takes an accent on e:

anel → anéis (ring → rings)

When stress falls on an earlier syllable, the accent remains where it already was:

automóvel → automóveis (car → cars)

Words ending in -ol

The -ol subgroup behaves in the same way. The l is dropped, -is is added, and an accent appears when stress falls on the final syllable:

lençol → lençóis (bedsheet → bedsheets)

Words ending in -ul

Words ending in -ul are relatively uncommon, but the plural is formed regularly. The l disappears and -is is added, with no accent change:

azul → azuis (blue → blues)

Words ending in -il

The -il subgroup is the exception. Here, plural formation depends directly on stress placement.

If the word is stressed on the final syllable, the l disappears and only -s is added, since the i is already present:

imbecil → imbecis (imbecile → imbeciles)

If the word is not stressed on the final syllable, both i and l disappear and are replaced by -eis:

versátil → versáteis (versatile → versatile [plural])

This stress-based distinction makes -il words less predictable than the other groups. In all other cases, Portuguese words ending in l form the plural by replacing l with -is.

What learners say

I love the mix of formats. The listening pieces, short reads, exercises, and idioms cover different angles, so I don't get stuck doing the same thing. It keeps me coming back.

~ Olivia ~

It doesn’t feel like studying in the boring sense. The tone is light, but the practice is solid, and I’ve noticed I can put sentences together more easily.

~ Giulia ~

Everything feels well put together. I'll listen to something at my level, check a quick explanation when I'm confused, and then do a practice exercise. Everything I need is in one place and easy to find.

~ Liam ~

Portuguese used to feel messy, like I was putting in effort but not getting results. With Portuguesepedia, I can focus on what I actually need, and I’ve started noticing real improvement week by week.

~ Ebba ~

Something clicked after a few weeks. Real Portuguese started making more sense — not just on paper, but when I'm actually listening. I hadn't felt that kind of progress before.

~ Maria ~

I’d been trying to learn Portuguese for years, but I never felt confident using it. Textbooks were too much, and speaking classes made me freeze. With Portuguesepedia, things finally started to make sense.
