The patterns behind the things we say.
Code-switching is the use of more than one language or variety within a conversation or interaction. Speakers may shift with topic, audience, quotation, or social context; the pattern is meaningful language use, not evidence of confusion.
Diglossia is a pattern in which distinct varieties associated with the same language community have different conventional roles. It describes how varieties are distributed across settings, not a claim that one is inherently better.
Linguistics is the systematic study of human language: its sounds or signs, structure, meaning, use, and change. It asks how language works rather than simply prescribing how people should speak.
Psycholinguistics studies how the mind represents, understands, and produces language. It turns questions about word recognition, sentence planning, and comprehension into experiments that can test how language processes unfold.
Sociolinguistics studies how language varies with social life and how people interpret that variation. A simple observation of one phrase across settings can reveal how context, identity, and expectations shape language in use.
Grammatical gender is a system that assigns nouns to classes, often reflected in agreement on other words. Its categories need not correspond to a noun’s biological sex, and languages vary widely in how classification works.
Word order is the arrangement of sentence parts, especially subject, object, and verb. Languages use different basic patterns, and clues such as endings, context, and emphasis help show who did what.
