Language Learning Terminology and Knowledge Base

Mastering the specialized vocabulary of second language acquisition (SLA) empowers adult learners to understand research, navigate resources, and communicate effectively about their multilingual journey. This comprehensive knowledge base defines essential terms, frameworks, and concepts that form the foundation of modern language learning theory and practice.

Proficiency Frameworks and Assessment

Common European Framework of Reference (CEFR)

The CEFR is the international standard for describing language ability across six levels:

  • A1 (Beginner): Can understand and use familiar everyday expressions and basic phrases. Can introduce themselves and others and ask/answer questions about personal details.
  • A2 (Elementary): Can communicate in simple routine tasks requiring direct exchange of information. Can describe aspects of their background, immediate environment, and matters of immediate need.
  • B1 (Intermediate): Can understand main points of clear standard input on familiar matters. Can deal with most situations likely to arise while traveling. Can produce simple connected text on familiar topics.
  • B2 (Upper-Intermediate): Can understand complex text on both concrete and abstract topics. Can interact with fluency and spontaneity with native speakers. Can produce clear, detailed text on a wide range of subjects.
  • C1 (Advanced): Can understand demanding, longer texts and recognize implicit meaning. Can express themselves fluently and spontaneously without searching for expressions. Can use language flexibly for social, academic, and professional purposes.
  • C2 (Proficiency/Mastery): Can understand virtually everything heard or read. Can summarize information from different sources, reconstructing arguments and accounts coherently. Can express themselves spontaneously, precisely, and fluently, differentiating finer shades of meaning.

ACTFL Proficiency Guidelines

The American Council on the Teaching of Foreign Languages provides an alternative proficiency scale including Novice, Intermediate, Advanced, Superior, and Distinguished levels, with subcategories (Low, Mid, High) providing additional granularity.

ILR Scale

The Interagency Language Roundtable (ILR) scale, used by U.S. government agencies, rates proficiency from 0 (no proficiency) to 5 (functionally native), with plus levels (+) indicating emerging competence at the next level.

Types of Multilingualism

Bilingualism

The regular use of two languages in daily life. Subtypes include:

  • Simultaneous bilingualism: Learning two languages from birth
  • Sequential bilingualism: Learning a second language after establishing first language competence
  • Balanced bilingualism: Equal proficiency in both languages
  • Dominant bilingualism: Greater proficiency in one language
  • Receptive bilingualism: Understanding but not speaking a second language

Multilingualism

The use of three or more languages. Research suggests cognitive benefits compound with additional languages, though maintenance becomes increasingly demanding.

Plurilingualism

The CEFR concept emphasizing the integrated competence of a speaker who has multiple languages at their disposal, rather than viewing languages as separate systems.

Second Language Acquisition Concepts

Comprehensible Input (i+1)

Stephen Krashen's concept that language acquisition occurs when learners receive input slightly beyond their current level (i+1). Input must be comprehensible—understood through context, gestures, or prior knowledge—to drive acquisition.

Output Hypothesis

Merrill Swain's theory that producing language (speaking and writing) drives acquisition by forcing learners to process language syntactically, notice gaps in knowledge, and test hypotheses about the target language.

Noticing

Richard Schmidt's concept that conscious attention to linguistic features in input is necessary for them to be acquired. Learners must notice a form before it can become intake.

Interlanguage

The systematic linguistic system that second language learners construct as they acquire a new language. Interlanguage represents a stage between the native and target languages, with its own consistent rules and structures.

Fossilization

The process by which certain non-target forms become fixed in a learner's interlanguage, resisting change despite continued exposure to the target language. Fossilized errors often persist even at advanced proficiency levels.

Transfer

The influence of one language on another:

  • Positive transfer: Facilitation when L1 and L2 share features
  • Negative transfer (interference): Hindrance when L1 and L2 differ
  • Cross-linguistic influence: Broader term encompassing all types of language interaction

Language Transfer

The carryover of linguistic features, processing strategies, or pragmatic norms from one language to another. Transfer can occur from L1 to L2, L2 to L1, or among multiple L2s.

Learning Theories and Models

Monitor Model

Stephen Krashen's five hypotheses about SLA:

  • Acquisition-Learning Hypothesis: Distinction between subconscious acquisition and conscious learning
  • Monitor Hypothesis: Conscious learning serves only as an editor/monitor for production
  • Natural Order Hypothesis: Grammatical structures are acquired in predictable sequences
  • Input Hypothesis: Acquisition occurs through comprehensible input (i+1)
  • Affective Filter Hypothesis: Emotional factors can block input from reaching acquisition mechanisms

Interaction Hypothesis

Michael Long's theory that modified interaction—negotiation of meaning between speakers—facilitates acquisition by making input comprehensible and drawing attention to form.

Noticing Hypothesis

Richard Schmidt's proposal that conscious noticing of linguistic forms in input is a necessary condition for language learning, though not sufficient alone.

Sociocultural Theory

Based on Vygotsky's work, this perspective views language learning as socially mediated development. The Zone of Proximal Development (ZPD) represents tasks learners can complete with assistance, indicating readiness for learning.

Language Skills

Receptive Skills

Language processing that involves receiving input:

  • Listening comprehension: Understanding spoken language
  • Reading comprehension: Understanding written text

Productive Skills

Language processing that involves producing output:

  • Speaking: Oral production of language
  • Writing: Written production of language

Integrated Skills

Activities combining multiple skills, such as reading then writing a response, or listening and then speaking about content.

Teaching Methodologies

Grammar-Translation Method

Traditional approach emphasizing explicit grammar instruction, translation exercises, and memorization of vocabulary lists. Focuses on reading and writing over speaking.

Audio-Lingual Method

Behaviorist-based approach using repetition, drills, and pattern practice to form language habits. Emphasizes spoken language and correct pronunciation.

Communicative Language Teaching (CLT)

Approach prioritizing communication over grammatical perfection. Uses authentic materials, information-gap activities, and learner-centered instruction.

Task-Based Language Teaching (TBLT)

Method organizing instruction around meaningful tasks that mirror real-world language use. Learners use language to accomplish communicative goals.

Content and Language Integrated Learning (CLIL)

Approach teaching subject matter through the target language, simultaneously developing content knowledge and language proficiency.

Cognitive and Affective Factors

Language Learning Aptitude

An individual's natural ability to learn foreign languages, comprising:

  • Phonetic coding ability
  • Grammatical sensitivity
  • Inductive language learning ability
  • Memory for speech sounds

Motivation

The driving force behind language learning effort. Types include:

  • Integrative motivation: Desire to integrate with target language culture
  • Instrumental motivation: Practical goals (career, education)
  • Intrinsic motivation: Internal satisfaction from learning
  • Extrinsic motivation: External rewards or pressures

Language Anxiety

Worry and negative emotional reaction when learning or using a second language. Can significantly impact performance and willingness to communicate.

Learning Strategies

Deliberate actions learners take to improve their learning:

  • Cognitive strategies: Mental operations (note-taking, repetition)
  • Metacognitive strategies: Planning, monitoring, evaluating learning
  • Social strategies: Learning with others (cooperation, questions)
  • Affective strategies: Managing emotions (relaxation, self-encouragement)

Additional Terms

False Friends (Faux Amis)

Words in different languages that look or sound similar but have different meanings (e.g., "actual" in English vs. "actual" in Spanish).

Cognates

Words in different languages that share common etymological origins and similar meanings, facilitating vocabulary acquisition.

Code-Switching

Alternating between languages within a conversation, sentence, or even single utterance. Common among multilingual speakers.

Formulaic Sequences

Prefabricated chunks of language stored and retrieved whole, such as greetings, idioms, or conversational routines.

Pragmatics

The study of language use in social contexts, including politeness, speech acts, and culturally appropriate communication.

Pruning

The brain's process of eliminating unused neural connections, which can affect accent retention if language learning begins after childhood.
