Language Arts and Added Languages

ELA / PLA — the names we give the learner, and what the sorting does with them.
A learner of English is called different things depending on where she is, how old she is, and who is doing the naming. The names are not synonyms. Each was made to describe a situation. This book starts with the names because the Notice in Chapter 1 depends on confusing them.

Chapters

Preface

Where a learner lives decides the label. A student surrounded by English, who needs it for the bus, the clinic and the school office, is an ESL or ELL student. A student far from English, who studies it as a subject, is an EFL student. A child of an immigrant household who speaks one language at home and another at school belongs to neither box cleanly, and the heritage-language literature exists because of that child. In Brazil the same distinctions run through Português como Língua Adicional (PLA), Estrangeira (PLE), Segunda Língua (PL2), Acolhimento (PLAc) and Herança (PLH).

Each label was made to describe a learner’s situation. The satire in Chapter 1 does the opposite: its Specialist uses them as a verdict on a person’s origin.

Prefácio

O lugar onde o aprendiz vive decide o rótulo. Um aluno cercado de inglês, que precisa dele para o ônibus, a clínica e a secretaria da escola, é um aluno de ESL ou ELL. Um aluno distante do inglês, que o estuda como disciplina, é um aluno de EFL. A criança de uma família imigrante que fala uma língua em casa e outra na escola não cabe direito em nenhuma das duas caixas, e a literatura sobre língua de herança existe por causa dela. No Brasil as mesmas distinções passam por Português como Língua Adicional (PLA), Estrangeira (PLE), Segunda Língua (PL2), Acolhimento (PLAc) e Herança (PLH).

Cada rótulo foi feito para descrever a situação de um aprendiz. A sátira do Capítulo 1 faz o contrário: seu Especialista os usa como veredito sobre a origem de uma pessoa.

Glossary / Glossário

English termWhat it meansPortuguese counterpart
ELAEnglish Language Arts: the school subject for students whose home language is English (reading, writing, literature)Língua Portuguesa (the school subject)
EFLEnglish as a Foreign Language: English learned where it is not the everyday language, e.g. a student in BrazilPLE, Português como Língua Estrangeira
ESLEnglish as a Second Language: English learned inside an English-speaking country, usually by immigrants and their childrenPL2, Português como Segunda Língua; PLAc, Português como Língua de Acolhimento (migrants and refugees arriving in Brazil)
ELLEnglish Language Learner (also EL, English Learner): the US K-12 label for the student, not the programNo single term; the learner is described through PLA, PL2 or PLAc
EALEnglish as an Additional Language: the UK and Australian term for the same learners as ESL; avoids “second” for a child who already speaks several languagesPLA, Português como Língua Adicional (also called PFOL, Português para Falantes de Outras Línguas, especially in university extension projects)
ENL / ELD / ESOLLocal program names: New York’s English as a New Language, California’s English Language Development, English for Speakers of Other LanguagesPFOL, Português para Falantes de Outras Línguas (the source gives PFOL as another name for PLA; matching it to ESOL is this book’s own reading)
Heritage speakerSomeone who speaks a family language at home but was schooled in anotherPLH, Português como Língua de Herança
(umbrella)Learning a language that is not one’s mother tongue; no single English label is claimed herePLNM, Português como Língua Não Materna: the source treats PLE, PLA, PL2, PLH and PLAc as kinds of PLNM
World LanguagesThe US school label for non-English language classes, formerly “foreign languages”Língua Adicional (used in some Brazilian curricula)
Status of these definitions

The English-side definitions are standard usage from the author’s own knowledge and are not yet checked against sources. The Portuguese terms (PLE, PLA, PFOL, PL2, PLH, PLAc and the umbrella PLNM) were checked on 2026-10-22 against one article: Rocha & Ribeiro, (Con)Textos Linguísticos 19(42), 2025, p. 163. That article cites Fontana, Camargo and Nunes (2022) for them, so it is only a secondary source; the primary source has not been read. It does not support two claims in the table: that “Língua Adicional” is used in some Brazilian curricula for world languages, and that ELL has no single Portuguese term. Both stay unverified. Before print, check the federal wording of “English learner” in US law and the program names New York and California actually use. Starting points: Reading Horizons on ESL, EFL, ESOL, ELL and ESP; Contextos Linguísticos (UFES).
