Is my understanding on the negativity of intrapleural pressure CORRECT?

[StrongBeliever]

so in my textbook it says, 'intrapleural pressure is more negative in the apex of the lung than in the base'.

Now cos the alveoli in the apex is larger, there's less space in the intrapleural space, and therefore the pressure within the intrapleural space increases or 'more negative'?

From what i understand, negative means less than the atmospheric pressure,
so does negative also refer to an increase of pressure too?
