What does syntax mean?
Syntax is the system of rules that determines how words and phrases are arranged to form meaningful expressions in a language. It covers matters such as word order, agreement, and the relationships between clauses, allowing speakers and writers to communicate clearly and predictably. The word is also widely used in computing, where it refers to the formal structure of statements in a programming language and to the rules that determine whether code is valid. Syntax is distinct from semantics: syntax concerns how an expression is formed, while semantics concerns what it means. Although the term is specialized and usually appears in academic, technical, or editorial contexts, understanding syntax is useful for studying language, improving writing, reading formal grammar, and programming. It can also refer more broadly to the structural organization or arrangement of any complex system.
nounThe rules and principles governing the arrangement of words and phrases in a language; in computing, the corresponding grammatical structure of a programming language.
- The principles and rules governing the arrangement of words and phrases in a language.
- The formal grammatical rules and structure used to write statements in a programming language.
"Clear syntax makes a complex argument easier to follow."
"Careful syntax makes a complex argument easier to follow."
"The compiler reports an error in the syntax of the program."
The plural is grammatically standard but uncommon in ordinary use.
"The study compared the syntaxes of several closely related languages."
Syntax is the invisible architecture that gives language its shape—and the reason a program can be perfectly meaningful yet still fail to run.

Where does syntax come from?
The English word comes through Latin from Greek syntaxis, meaning “a putting together” or “arrangement,” ultimately from Greek roots meaning “to put together” or “to arrange.” The term entered English in the seventeenth century and was initially associated with grammatical arrangement. Its Greek element also connects it with related words concerning order, arrangement, and classification, such as taxis, taxon, and taxonomy.

How syntax is actually used
Usually formal or technical. In linguistics, syntax specifically concerns sentence structure rather than vocabulary or meaning; in computing, it describes the permitted form of program statements and expressions.
Easily confused with syntax
Syntax concerns the form and arrangement of words or symbols, whereas semantics concerns their meaning.
