Multilingual
To be proficient in more than one language

To be proficient in more than one dialect or variety of the same language

Bilingualism provides some protection from cognitive diseases like Alzheimer’s.
Bilingual children often outperform monolingual children in cognitive tasks and social problem solving.
Children who are proficient in their heritage language often have higher self-esteem, more solid family relationships, and are less likely to drop out of high school.

4. Evidence from Research and Principles from Linguistics Tell Us…
Only fluent bilinguals truly code-switch. 
Spanglish is a rule-governed system that has great expressive potential and that is used by many fluent bilinguals for a complex set of reasons.
Not all bilinguals (even very fluent bilinguals) can translate or interpret easily because this is a skill that has to be cultivated, and not an automatic part of bilingualism.
