This document discusses second language acquisition (SLA). It defines SLA as the process of learning a second language and notes it is also the scientific discipline devoted to studying that process. The document distinguishes between a second language, foreign language, library language, and auxiliary language. It also defines and compares first language acquisition and multilingual acquisition. Theories of language acquisition discussed include behaviorism, nativism, and Krashen's theory of second language acquisition.

2. What is SAL?
• Second-language acquisition (SLA), second-
language learning, or L2 (language2) acquisition, is the
process by which people learn a second
language. Second-language acquisition is also the
scientific discipline devoted to studying that process.

3. • A second language: is typically an official or societally
dominant language needed for education, employment, and
other basic purposes.
• A foreign language: is one not widely used in the learners’
immediate social context which might be used for future
travel or other crosscultural communication situations.
• A library language:is one which functions primarily as a tool
for further learning through reading, especially when books
or journals .
• An auxiliary language: is one which learners need to know
for some official functions in their immediate political
setting, or will need for purposes of wider communication.
Distinctions commonly made in
the literature:

4. What is First Language?
 The concepts first language, native language,
primary language, and mother tongue.
The distinctions are not always clear-cut.
For purposes of SLA concerns, the important
features that all shades of L1s share are that
they are assumed to be languages which are
acquired during early childhood – normally
beginning before the age of about three years
and that they are learned as part of growing up
among people who speak them.
 Acquisition of more than one language
during early childhood is called simultaneous
multilingualism, to be distinguished from
sequential multilingualism.

5. Acquisition & Learning
• Acquisition: Gradual
development of a language
+occurs in a naturally
Communicative Situation with
other.
• Learning :
Conscious process of
Accumulating Knowledge of
Vocabulary and Grammar + in
Institutional Setting.

6. What are theories of language
acquisition?
• Language acquisition is the process by which
humans acquire the capacity to perceive and
comprehend language, as well as to produce
and use words and sentences to
communicate. Language acquisition is one of
the quintessential human traits, because non-
humans do not communicate by using language.

• 2) Behaviorism Theory
• 3) Nativist

9. Krashen’s theory of Second
language Acquisition
• Acquisition Learning hypothesis
• Monitor hypothesis
• Natural Order hypothesis
• Input hypothesis
• Affective Filter hypothesis

10. Conclusion
• In this Chapter, Describe the emergence of as a discipline from
early work in CA error analysis and inter language development .
• The chapter also looks at the practical implications of current
research for syllabus design, and methodology, focusing in
particular.
• On the implications of SLA research for syllabus design, the input
hypothesis, and task-based language teaching. The final part of
the chapter suggests that future work will attempt to capture the
complexity of the acquisition.
• process by incorporating a wide range of linguistic, social,
interpersonal and psycholinguistic variables into the design of the
research process.
