I used to start learning a few languages, admittingly my interest ,stamina and brain force didn't last for more than a couple of days each.
Nethertheless, I noticed , that the different grammars explained clauses being divided into Subject and Verbs as their minimal requirements.
Now, Subject is a sentence part and verb is a part of speach, furthermore other definitions of clauses name Subject and Predicative as the minimal requirements for a clause , which is a blessing feeling of absence of cognitive dissonance since in this case both are sentence parts.
But why is it so?
