A bilingual speaker switches from English to Spanish mid-sentence: 'I need to hablar with you about something importante.' A monolingual observer concludes the speaker lacks full proficiency in either language. This conclusion is:
ACorrect — mixing languages indicates incomplete acquisition of at least one
BIncorrect — code-switching follows grammatical rules and requires high competence in both languages
CPartly correct — the speaker likely has high English proficiency but weaker Spanish
DCorrect only if the switch occurs within a single clause rather than between sentences
Intrasentential code-switching (within a sentence) is actually the most demanding form of bilingual behavior. It requires the speaker to obey the grammatical rules of both languages simultaneously and to execute switches at grammatically permitted boundaries. The Matrix Language Frame model explains that one language provides the structural skeleton while the other contributes embedded elements — a system that collapses if either language is insufficiently mastered. The monolingual observer's intuition reverses the truth.
Question 2 Multiple Choice
According to Myers-Scotton's Matrix Language Frame model, what determines which language 'controls' an intrasentential code-switch?
AWhichever language the speaker has higher overall proficiency in
BThe language that provides the grammatical skeleton, morphology, and phrase structure rules
CWhichever language contributes more content words to the utterance
DThe language the conversation began in
The MLF model proposes that one language (the matrix language) provides the morphosyntactic frame — the inflectional morphology, function words, and phrase structure rules. The other language (the embedded language) contributes content items (nouns, verbs) within that frame, but must conform to the matrix language's structure. This is why code-switches respect grammatical constraints: the switch never violates the matrix language's morphology.
Question 3 True / False
Bilingual children typically show delayed language development compared to monolingual children because they is expected to learn two systems simultaneously.
TTrue
FFalse
Answer: False
This is one of the most persistent myths about bilingualism. Bilingual children may have smaller vocabularies in each individual language than same-age monolinguals in that language, but their total vocabulary across both languages is comparable to or larger than monolingual peers. Overall language development milestones — first words, grammatical complexity, discourse competence — follow the same timelines. The appearance of delay in one language dissolves when both languages are counted.
Question 4 True / False
Language attrition — the erosion of a language through reduced use — can often be reversed with renewed exposure to that language.
TTrue
FFalse
Answer: True
Attrited features tend to re-emerge with renewed exposure, suggesting the underlying competence persists in a weakened or suppressed state rather than being deleted. This is especially true for core grammar, which is more resistant to attrition than phonology or low-frequency vocabulary. The 'use it or lose it' description is accurate, but so is 'reactivation' — attrition is gradient and reversible rather than a one-way door.
Question 5 Short Answer
Why does code-switching require high competence in both languages rather than indicating deficiency in either?
Think about your answer, then reveal below.
Model answer: To code-switch fluently, a speaker must simultaneously monitor two grammatical systems, apply the correct morphology from the matrix language, select appropriate switch points (typically major constituent boundaries that preserve both languages' structure), and manage the social pragmatics of switching. Errors that violate either language's grammar essentially do not occur naturally among competent bilinguals. This dual-system control demands more linguistic knowledge, not less — beginners with partial competence cannot do it.
The misconception persists because mixing feels like losing control to a monolingual observer. In reality, the regulation of when and how to switch is itself a sophisticated competence. Research consistently shows that code-switching frequency correlates with higher proficiency in both languages, not lower. Unskilled speakers cannot switch fluidly — they get stuck or produce ungrammatical blends.
