The document discusses the types of errors in second language acquisition, categorizing them into interlingual transfer, intralingual transfer, context of learning, and communication strategies. Interlingual errors arise from mother-tongue influence, while intralingual errors include various learning strategy-based mistakes like false analogy and overgeneralization. The context of learning and learners' communication strategies, such as avoidance and appeal to authority, also significantly impact the language learning process.

1. Types of errors
Among the most frequent sources of errors Brown counts
(1) interlingual transfer,
(2) intralingual transfer,
(3) context of learning,
and (4) various communication strategies the learners use

2. Interlingual transfer
• Mother-tongue influence, causes interlingual errors.They are
very frequent at the initial stages of L2 Learning since the L1 is
the only language system the learner knows and can draw on and
therefore negative transfer takes place .Brown also argues that
when one is learning L3, L4 etc., transfer takes place from all
the previously learnt languages but the degree of transfer is
variable

3. Intralingual errors
Errors that result from L2 itself
James (1980: 185-187) goes into more details. He refers to
intralingual errors as learning-strategy based errors and lists 7
types of them:
False analogy, misanalysis, incomplete rule application, exploiting
redundancy,over-laboration,hypercorrection and
overgeneralization.

4. Intralingual errors
•· False analogy :
It arises when the learner incorrectly thinks that a new item behaves
like another item already known to him or her. For example the learner
already knows that dogs is plural from dog, so he or she thinks that
*sheeps is plural from sheep.

5. Intralingual errors
•Misanalysis:
It means that the learner has formed an unfounded hypothesis in
the L2 and is putting it in practice. James (1980: 185) gives as an
example the situation when the learner assumes that *its can be
used as a pluralized form of it

6. Intralingual errors
• Incomplete rule application:
It happens when the learner doesn't apply all the rules necessary to
apply in a particular situation. In fact, it is the converse of
overgeneralization
•Exploiting redundancy :
It appears because there is a lot of redundancy in every language, e.g.
unnecessary morphology, and intelligent learners try to avoid those
items which they find redundant to make their learning and
communication easier.

7. Intralingual errors
• Over-laboration :
Overlooking co-ocurrence restrictions means that the learner doesn't know that certain
words go together with certain complements, prepositions etc. An example given by James
(1998: 186) is when the learner ignores that the verb to enjoy is followed by gerund and not
bare infinitive.
• Hypercorrection, as James argues (1998: 186), "results from the learners over-monitoring their L2 output". ·
Overgeneralization means that the learner uses one member of a set of forms also in situations when the other
members must be used. This usually leads to overuse of one form and underuse of the others. Well known
candidates for overgeneralization are pairs as other/another, much/many, some/any etc. (James 1998: 187) -
the learner uses one of them instead of distinguishing between them and using each in the appropriate
situation. Overgeneralization of language rules is also common, e.g. *Does she can dance? reflects that the
learner overgeneralizes the use of auxiliary verbs in questions.

8. Context of learning
• It refers to the setting where a language is learnt, e.g. a
classroom or a social situation, and also to the teacher and
materials used in the lessons. As Brown explains, "students often
make errors because a misleading explanation from the teacher,
faulty presentation of a structure or word in a textbook, or even
because of a patent that was rotely memorized in a drill but not
properly contextualized"

9. Communication strategies the learners use
• Communication strategies are consciously
used by the learners to get a message
across to the hearer. They can involve both
verbal and non-verbal communication
mechanisms (Brown 1980: 178).
We distinguish among the following
communication strategies:

10. Communication strategies the learners use
• Avoidance arises when a learner consciously avoids certain language item because he feels uncertain
about it and prefers avoiding to committing and error. There are several kinds of avoidance, e.g.
syntactic, lexical, phonological or topic avoidance (Brown 1980: 178-179).
• Prefabricated patterns are memorized phrases or sentences, as in 'tourist survival' language or a
pocket bilingual phrasebook, and the learner who memorized them usually doesn't understand the
components of the phrase
• · Cognitive and personality styles can also cause errors. For instance, Brown (1980: 180) suggests that
"a person with high self-esteem may be willing to risk more errors, in the interest of communication,
since he does not feel as threatened by committing errors as a person with low self-esteem". ·Appeal
to authority is a strategy when the learner, because of his uncertainty about some structure, directly
asks a native speaker, a teacher or looks up the structure in a bilingual dictionary (Brown 1980: 180).
· Language switch is applied by the learner when all the other strategies have failed to help him or
her. So the learner uses his or her native language to get the message across, regardless of the fact
that the hearer may not know the native language (Brown 1980: 181)
