+POS (Parts Of Speech) are lexical categories which we attach to words, equivalent to gramatical classes.

+Constituents have a common behaviour, in this case, the noun phrases can appear before verbs
+
+## Context-free grammars

+The constituents can be formalized.
+These are production rules and are composed of **non-terminals** (noun, phrase, det, etc.) and **terminal** symbols (words or symbols in the language)
+
+*Symbol* -> *non-terminals* and/or *terminals*
+
+The rules are used for generation or assigning structure.  
+Constituents form higher-level constituents.
