Syntax vs. semantics: what’s the diff?

Syntax and semantics are two different concepts in language. Syntax deals with how words fit together in a sentence, while semantics is the study of single words or symbols and how they are perceived. Understanding these concepts is important in language and communication fields. Semantics includes connotations and associations, while syntax includes grammar and phrasing. Both are useful in linguistics and can be used together to build language models for research purposes.

When it comes to how people use language to identify ideas and concepts, syntax and semantics play two different roles and mean two completely different things. Where syntax deals with how words or phrases fit together in a sentence, perhaps even semantically, semantics is the study of any single word, icon or symbol and how it is perceived by the mind. Knowing the difference between these fundamental concepts of syntax and semantics can benefit anyone involved in the humanities related to language or communications.

Understanding the difference between syntax and semantics also requires a developed understanding of each of these two ‘data types’ or ‘cognitive protocols’. The first, syntax, is related to the grammar, phrasing, punctuation, and other elements of a language that exactly influence how people use and understand that language. For example, considering how phrasal verbs consist of a simple verb and a simple preposition is a syntax problem.

An example of semantics is a juxtaposition of two symbols or verbal/visual elements. Humans make choices about interpreting semantics based on fixed associations and learned associations. Semantic context can be important, for example, in the production of consumer goods that use symbols to communicate to a worldwide consumer base, rather than using the words and conventions of a single nation.

To further define semantics, experts often refer to the connotations of words and symbols as a search for semantics. Semantics again refers to the idea that units of discourse have meaning and can apply to a single unit or to the linking of two units. Some academics and others refer to fields such as philology that study the use of words or ideas as semantic in nature.

Both syntax and semantics are useful in the general realm of linguistics. To distinguish the common roles of both syntax and semantics, an academic could use syntax to study whether word linking is correct, and semantics to generally understand how multiple words are perceived when presented together in a given order. Linguists can use a combination of semantic and syntactic study to build language models for many different research uses. These may also feature prominently in research proposals aiming to further define practical uses of known linguistic structures.
