A second language (L2) is a language spoken in addition to one's first language (L1). A second language may be a neighbouring language, another language of the speaker's home country, or a foreign language. A speaker's dominant language, which is the language a speaker uses most or is most comfortable with, is not necessarily the speaker's first language. For example, the Canadian census defines first language for its purposes as "the first language learned in childhood and still spoken", recognizing that for some, the earliest language may be lost, a process known as language attrition. This can happen when young children start school or move to a new language environment.
English as a second or foreign language is the use of English by speakers with different native languages, often with students whose native language is not English and are learning to speak and write English, commonly among students. Language education for people learning English may be known as English as a foreign language (EFL), English as a second language (ESL), English for speakers of other languages (ESOL), English as an additional language (EAL), or English as a new language (ENL), which refers to the practice of studying English in a country where it is not the dominant language. These programs, especially ESL, are usually an academic subject, course, or program designed to teach English to students who are not yet proficient in the language. While some people only refer to learning in an English-speaking country, learning this language can also entail learning in a non-English speaking or non-native nation.

Second-language acquisition (SLA), sometimes called second-language learning—otherwise referred to as L2acquisition, is the process by which people learn a second language. Second-language acquisition is also the scientific discipline devoted to studying that process. The field of second-language acquisition is regarded by some but not everybody as a sub-discipline of applied linguistics but also receives research attention from a variety of other disciplines, such as psychology and education.
An interlanguage is an idiolect which has been developed by a learner of a second language (L2) which preserves some features of their first language (L1) and can overgeneralize some L2 writing and speaking rules. These two characteristics give an interlanguage its unique linguistic organization. It is idiosyncratically based on the learner's experiences with L2. An interlanguage can fossilize, or cease developing, in any of its developmental stages. It is claimed that several factors shape interlanguage rules, including L1 transfer, previous learning strategies, strategies of L2 acquisition, L2 communication strategies, and the overgeneralization of L2 language patterns.
The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977.
Michael Swan is a writer of English language teaching and reference materials. He graduated from University of Oxford with a bachelor's degree in modern foreign languages and has later gone for a postgraduate research degree. He is the founder of Swan School of English.
The noticing hypothesis is a theory within second-language acquisition that a learner cannot continue advancing their language abilities or grasp linguistic features unless they consciously notice the input. The theory was proposed by Richard Schmidt in 1990.
Vivian James Cook was a British linguist who was Emeritus Professor of Applied Linguistics at Newcastle University. He was known for his work on second-language acquisition and second-language teaching, and for writing textbooks and popular books about linguistics. He worked on a number of topics such as bilingualism, EFL, first-language acquisition, second-language teaching, linguistics, and the English writing system. He published more than 20 books and 100 papers. He was founder and first President of the European Second Language Association (EuroSLA), and co-founder of the Oxford University Press journal Writing Systems Research. He died in December 2021, at the age of 81.
Paul Nation is an internationally recognized scholar in the field of linguistics and teaching methodology. As a professor in the field of applied linguistics with a specialization in pedagogical methodology, he has been able to create a language teaching framework to identify key areas of language teaching focus. Paul Nation is best known for this framework, which has been labelled The Four Strands. He has also made notable contributions through his research in the field of language acquisition that focuses on the benefits of extensive reading and repetition as well as intensive reading. Nation's numerous contributions to the linguistics research community through his published work has allowed him to share his knowledge and experience so that others may adopt and adapt it. He is credited with bringing « legitimization to second language vocabulary researches » in 1990.
Second-language acquisition classroom research is an area of research in second-language acquisition concerned with how people learn languages in educational settings. There is a significant overlap between classroom research and language education. Classroom research is empirical, basing its findings on data and statistics wherever possible. It is also more concerned with what the learners do in the classroom than with what the teacher does. Where language teaching methods may only concentrate on the activities the teacher plans for the class, classroom research concentrates on the effect the things the teacher does has on the students.
The interaction hypothesis is a theory of second-language acquisition which states that the development of language proficiency is promoted by face-to-face interaction and communication. Its main focus is on the role of input, interaction, and output in second language acquisition. It posits that the level of language that a learner is exposed to must be such that the learner is able to comprehend it, and that a learner modifying their speech so as to make it comprehensible facilitates their ability to acquire the language in question. The idea existed in the 1980s, and has been reviewed and expanded upon by a number of other scholars but is usually credited to Michael Long.
Language learning strategies is a term referring to the actions that are consciously deployed by language learners to help them learn or use a language more effectively. They have also been defined as "thoughts and actions, consciously chosen and operationalized by language learners, to assist them in carrying out a multiplicity of tasks from the very outset of learning to the most advanced levels of target language performance". Some learning strategies include methods that facilitate lowering the learner's language anxiety, therefore improving their confidence in using the language. Consistently it has been proven that strategies, those mentioned in the following article and others, assist learners to become more proficient. The term language learner strategies, which incorporates strategies used for language learning and language use, is sometimes used, although the line between the two is ill-defined as moments of second language use can also provide opportunities for learning.
The natural approach is a method of language teaching developed by Stephen Krashen and Tracy Terrell in the late 1970s and early 1980s. The Natural Approach has been used in ESL classes as well as foreign language classes for people of all ages and in various educational settings, from primary schools to universities. It aims to foster naturalistic language acquisition in the classroom setting by emphasizing communication and limiting conscious grammar study and explicit correction of student errors. Efforts are also made to make the learning environment as stress-free as possible, by lowering the affective filter. In the natural approach, language output is not forced, but allowed to emerge spontaneously after students have attended to large amounts of comprehensible language input. Comprehensible input is the content that language learners are exposed to in the target language. Krashen suggests that language learners should be able to understand the comprehensible input provided at their current levels of language acquisition, while also making it as interesting and engaging as possible.

The Teachability Hypothesis was produced by Manfred Pienemann. It was originally extracted from Pienemann's Processibility model. It proposes that learners will acquire a second language (L2) features if what is being taught is relatively close to their stage in language development.
Mary J. Schleppegrell is an applied linguist and Professor of Education at the University of Michigan. Her research and praxis are based on the principles of Systemic Functional Linguistics (SFL), a theory derived from the work of social semiotic linguist Michael Halliday. Schleppegrell is known for the SFL-based literacy practices she has continuously helped to develop for multilingual and English language learners throughout her decades long career, which she began as an educational specialist before transitioning to the field of applied linguistics. As a result, her publications demonstrate a deep understanding of both the theories and practices related to teaching and learning.
