Commonsense definitions

A small point - 
Consider this sentence - The lawyer is talking. 
Immediately this conjures up an image in the mind of a lawyer in a courtroom wearing a lawyer's dress and arguing.

But this could also mean that a man is talking in his sleep, and is a lawyer by profession. Things would still mean - "The lawyer is talking". But we dont visualise that. Why?

Because : have a look at the very definitions of words in a dictionary. How does a dictionary describe definitions of words - we have phrases like "when someone...", "when something...", "when one.....", "(word) relating to...", "(word) used to indicate....", "used to mean...." etc. But what's hidden behind this 'relating to' and 'used to indicate' and 'used to mean'? What's hidden is 'USUALLY'! 'In typical/normal scenarios!' Even the phrases "when someone", "when something is so and so way it is called....." have the implicit connotation of "usually", "in typical scenarios", "in regular cases" etc. And what does all that - the hidden stuff and the implicit connotations indicate - Commonsense! Meaning commonly, usually, typically, in normal scenarios....etc.

So, if the very definitions of the words in the dictionary are "commonsense definitions", the visuals of the sentences too have to be commonsensical and typical. 

Speaking the other way, even my phone can be named as 'lawyer'! If such possibilities are to be accommodated, the whole dictionary would turn wild !
