How long does it take to learn Portuguese?

The Foreign Service Institute, which trains American diplomats, expects 24 weeks of full-time study (552 class hours) to take an English speaker to professional working Portuguese. That is the shortest time it gives for any language, shared with Italian, Dutch and the Scandinavian languages; Spanish gets 30. But that one figure covers two things that move at different speeds. Reading Portuguese comes early, and for anyone who already speaks Spanish it comes sooner still. Understanding it spoken comes later, and that is what decides how long the whole thing takes.

What the 24 weeks are measured against

The FSI's figure is the time its students usually need to reach an integrated score of 3 (Speaking + Listening) on the ILR scale. That is a working level: you can follow a meeting, argue a point and handle what you did not expect. Its first category, "languages close to English", is where the shortest courses are:

Two details are easy to miss. The class hours are only part of the work: an FSI week is 23 hours in class and 17 hours of study on top, so 24 weeks is close to a thousand hours in all. And the FSI lists one "Portuguese". It does not say whether its course is Brazilian or European, or give the two separate figures, so nothing on its page says one variety is quicker to learn.

We looked for a second published figure from a Portuguese exam body. The University of Lisbon's CAPLE pages describe each of its exams, from CIPLE (A2) to DUPLE (C2), by level, length and fee. They do not say how many hours of study each one takes, so there is no second number to give here.

The reading clock: fast

You can count how quickly Portuguese becomes readable. In 426 million words of Brazilian film and television subtitles (OpenSubtitles 2018), the commonest word forms cover this much of what is said:

At every line Brazilian Portuguese needs fewer word forms than Spanish. The first thousand cover 76.8% of Brazilian dialogue. How many words you need to speak Portuguese gives the full curve and shows where the Brazilian and European lists part.

The listening clock: slow

The trouble is that the spelling does not reliably tell you the sound, so a word you can read is not yet a word you can hear. The best-known causes are covered in is Portuguese hard to learn: the nasal vowels, unstressed vowels that shrink, and t and d changing before an "ee" sound. A beginner also meets smaller ones, all in very common words. In most of Brazil:

The last row can be measured. In Brazilian subtitles tá is word number 363 and pra is 101, both well inside the first thousand. In Portugal's subtitles they are 2,434 and 859. A learner who studies only from writing meets está and para, then hears something else.

None of this is difficult once you know it. It only takes time, because you learn it by hearing a great deal of Portuguese, not by reading about it.

If you speak Spanish: a head start that stops at the ear

Here the two clocks separate the most. For reading, a Spanish speaker begins well ahead. Of the 1,000 commonest Spanish word forms, 223 are spelt exactly the same among Brazil's 1,000 commonest, and many more differ by one letter. Portuguese vs Spanish counts that overlap and lists the false friends inside it.

For listening, the head start is far smaller than people expect. In the University of Groningen's MICReLa study, Spanish listeners heard short texts read in Portuguese, in Portugal's variety, and had to fill in missing words. Those with almost no previous contact with Portuguese placed 35.7% of them. The researchers treat roughly 40% as the level at which a conversation becomes workable. Portuguese listeners with the same lack of contact, hearing Spanish, placed 62.0%. Can Portuguese speakers understand Spanish explains why the gap runs that way. For a Spanish speaker, the useful point is this: your Spanish saves you most of the reading clock and very little of the listening clock.

Spanish also brings habits that produce sentences which look right and are not:

Each of these takes a minute to learn and a long time to stop getting wrong. The FSI publishes no separate figure for Spanish speakers, so how much of its 24 weeks they can skip has not been measured. What the listening studies do show is which part they cannot skip.

How long it takes in our own course

Verbavia (our own course) teaches Brazilian Portuguese, free in any web browser, phone included. It teaches the words in frequency order, explains the grammar in English, and every lesson has reading and listening, with writing from lesson 7. All of the first 691 lessons are written by hand. At one lesson a day, the course levels begin here:

The shorter settings are not faster. They spread each written lesson over two or three days, with fewer new words per day (8 on Complete, 6 on Balanced, 4 on Essentials), so a shorter session means a longer course. Spoken forms such as tá, the vowels that go quiet and the nasal ão get lessons of their own early in A2, and from B1 the course adds a run of lessons built around listening, so the slow clock is trained from the start rather than left until the end.

So how long does it take?

• To read simple Portuguese: the quick part. The first thousand word forms cover 76.8% of Brazilian dialogue, and a Spanish speaker starts with much of that already known.
• To follow it spoken: this is the long part, and Spanish shortens it much less than it shortens reading. It is the part to start in the first week, not after the grammar.
• To work in it: the FSI's 24 weeks of full-time study, the shortest time it gives any language.

Choose one variety before you start the listening work. The differences between them are mostly in sound, as Brazilian vs European Portuguese shows. The most common Portuguese words are free to browse in frequency order. The two-minute Portuguese vocabulary test estimates how many you already know, which is worth doing first if you speak Spanish. The Portuguese course starts with those words. For other languages, the same question is answered for Spanish, and the easiest languages for English speakers puts them side by side.
