The main difference between Grammar and Punctuation is that the Grammar is a set of structural rules that governs the composition of clauses, phrases, and words in any given natural language and system of rules and traditions of using punctuation marks.
In linguistics, grammar (from Greek: γραμματική) is the set of structural rules governing the composition of clauses, phrases, and words in any given natural language. The term refers also to the study of such rules, and this field includes phonology, morphology, and syntax, often complemented by phonetics, semantics, and pragmatics.
Punctuation (formerly sometimes called pointing) is the use of spacing, conventional signs, and certain typographical devices as aids to the understanding and the correct reading, both silently and aloud, of handwritten and printed texts. Another description is: “The practice, action, or system of inserting points or other small marks into texts, in order to aid interpretation; division of text into sentences, clauses, etc., by means of such marks.”
In written English, punctuation is vital to disambiguate the meaning of sentences. For example: “woman, without her man, is nothing” (emphasizing the importance of men), and “woman: without her, man is nothing” (emphasizing the importance of women) have very different meanings; as do “eats shoots and leaves” (which means the subject consumes plant growths) and “eats, shoots, and leaves” (which means the subject eats first, then fires a weapon, and then leaves the scene). The sharp differences in meaning are produced by the simple differences in punctuation within the example pairs, especially the latter.
The rules of punctuation vary with language, location, register and time and are constantly evolving. Certain aspects of punctuation are stylistic and are thus the author’s (or editor’s) choice, or tachygraphic language forms, such as those used in online chat and text messages.
