I have no idea what the 'normal meaning' of these words is nor what 
their 'base meaning' is. English words have multiple meanings which are 
generally vaguely defined and it doesn't identify and particular meaning 
as the 'base meaning'.

That's entirely circular. You were trying to define P ⊢ Q. Just falling 
back on what it means 'in English' doesn't elucidate anything as 
'proves' means very different things in different contexts.

Mikko had wanted to know what "semantic entailment" means in absence of 
a model and you haven't answered this.
