The easiest Portuguese classics for learners

The easiest of the 39 books on ClickBook's Portuguese shelf is Dom Casmurro, Machado de Assis's novel about a jealous husband. It scores 53 out of 100, against a shelf median of 70. Every book here was measured from its full text, not from a sample.

"Easiest" needs two warnings. First, the score is relative: it ranks these 39 books against each other and nothing else. A Portuguese 53 cannot be compared with a score on another language's shelf, and there is no CEFR level for the Portuguese shelf at all. Second, these are unabridged originals and published translations, not graded readers. Even the easiest of them suits an intermediate learner, not a beginner. Books flagged for adult themes would be left out of this list; on the Portuguese shelf, none currently carries that flag.

A famous novel is the easiest

You might expect a canonical novel to sit near the hard end. Dom Casmurro sits at the very bottom: 78.1% of its running words are among the 2,000 commonest in the language, and its sentences average 15.8 words. Machado's earlier novel, Memorias Posthumas de Braz Cubas (the edition's spelling of Memórias Póstumas de Brás Cubas), is eighth, at 62. He is the only author with two books in the ten.

The other giants of Portuguese literature do not come close. Eça de Queirós's A Illustre Casa de Ramires scores 72, and Camões's Os Lusíadas scores 87, the second-hardest book on the shelf. Machado is famous for irony, not for difficult words, and the measurement only sees words and sentences.

The score is mostly vocabulary

All ten of the easiest books have a higher share of common words than the shelf median of 72.5%. Their figures run from 73.3% to 81.3%. At the other end, the 11 books in the hardest band, Demanding, have a median of 68.7%. A few points sound small, but each point is one more word in every hundred from outside the 2,000 commonest, across the whole book.

Sentence length matters less. Its correlation with difficulty on this shelf is 0.39, and only seven of the ten easiest books have shorter sentences than the shelf median of 18.8 words. The formula adds points only for sentences averaging more than 15 words, and never more than 14 points, but that is still enough to reorder the top of the list, as two old texts show. Saudades: história de menina e moça, Bernardim Ribeiro's sixteenth-century romance, has the commonest vocabulary on the whole shelf, at 81.3%. On vocabulary alone it would be the easiest book here, but its sentences average 29.0 words, so it comes third. The Chronica de El-Rei D. Affonso V has the second-commonest vocabulary, at 78.2%, but its sentences average 37.8 words, which earns the full 14 points, so it scores 66 and misses the ten.

Dialogue is counted but is not part of the score, and on this shelf it barely moves with difficulty: the correlation is 0.01. Most of these books have little of it. The shelf median is 4.2% of the text. Saudades is the exception, at 58.9%, the most of any book on the shelf.

Easy does not mean short

Length and difficulty are separate measurements, and on this shelf they have almost nothing to do with each other: the correlation is 0.06. The ten easiest books run from 16,922 words to 77,721. Five are shorter than the shelf median of 47,288 words and five are longer. The easiest book of all is a 9 h read at a learner's pace, and the fourth easiest, Transviado, is 10 h. If you want to finish something soon, look at the reading time as well as the score.

A translation and an adaptation

Two of the ten owe their stories to another language. As Minas de Salomão is the Portuguese translation of King Solomon's Mines, which H. Rider Haggard wrote in English. It scores 62. And Petronio is a Portuguese play by Marcelino Mesquita that, as its subtitle says, is freely drawn from Quo Vadis, the Polish novel by Henryk Sienkiewicz. As a play, it has the shortest sentences on the shelf, at 8.5 words.

The ten easiest, lowest score first

Score is the difficulty out of 100, against the other Portuguese books on the shelf. Common words is the share of the running text made of the 2,000 commonest words of the language. Reading time is at a learner's pace of 130 words a minute.

Where to start

If you have never finished a book in Portuguese, start with Petronio. Its score of 64 is the joint highest in the table, but it is the shortest book on the whole shelf, at 16,922 words and about 2 h, and its sentences are the shortest too. If you would rather have a story you may already know, take As Minas de Salomão: an adventure, 7 h, with sentences averaging 14.6 words. If you want real literature now, go straight to Dom Casmurro. It is the easiest book here, and at 9 h it is a fortnight of evenings, not a weekend.

Petronio is not the only one that is not a novel. Flores do Campo is a book of João de Deus's poems, and the Visitas is a devotional book with a reading for each day of the month. Each book page splits the text into ten equal spans and shows where the book gets harder, so check it before you commit: Dom Casmurro's hardest stretch is its opening, which means the first chapters are not a fair test of the rest.

After these

The full Portuguese shelf can be sorted by difficulty. The eight easiest books form the Gentle band. The next eight, scoring 64 to 69, form the Steady band. The last two books in the table are the first two of Steady, which leaves six more to move on to, from 3 h (Contos d'Aldeia and Raios de extincta luz) to 15 h (Portugal e Brazil).

What the score cannot see

The score counts words and sentences. Three things slip past it.

• Old spelling. Many of these editions predate the modern spelling reforms, and the titles show it: Posthumas, Braz, mez, extrahida. The common-words list comes from this shelf's own texts, so forms like these may not cost a book many points, but a learner used to modern Portuguese will notice them on every page.
• Subject matter. A devotional book and a play set in Nero's Rome can both measure easy and still be far from your own interests, which is a difficulty of its own.
• Style. Machado's words are plain and his narrator is not to be trusted. Common words do not make a book simple.

How books are measured sets out the formula and its other limits.
