A "grammar" (formal) is one, of many (formal and informal), precise
(formal) description of a language (syntax not semantic).

A "syntax of a formal language" defines exactly what symbols (language
symbols) sequences are correct expressions (words or sentences) of the
language, and associates a concrete syntax tree, containing all the
language terminals, to them. So, a "grammar" is one (of many) way of
description "syntax of a formal language". Thats mens, in many
situations both meanings can are equivalent bat not always.
