Grammar is not just syntax. It includes all of the following:
• Syntax, i.e. sentence structure, where we distinguish subjects and objects, subordinate and main clauses, and so on.
• Morphology, i.e. word structure, where we recognise roots, suffixes, inflected words, and so on.
• Semantics, i.e. meaning - the things, people, events and so on that we refer to when talking.
