We do not have to view Modal, Conditional, or Unreal Past patterns as separate. With Perfect tenses, our syntactic HAVE helps tell about real time. It has an open real-time frame. With the Unreal Past or Conditional, HAVE tells about hypothetical time. HAVE is not part the real map, then. It comes with an auxiliary compass for relative time.
. . . Let us think about Madame Règle. She has the potential to have lunch at Latimer Sauf’s restaurant every day. He always has a table for his friends and she has enough money. However, her work with Paris haute couture designers often keeps her over the lunchtime. Her coming to lunch is probable, but not certain. CERTAINTY requires both potentiality and probability.

We may find grammar books to tell about “stative” or “static verbs”. The books give lists of such verbs to remember and not to use with the Progressive.

We have our time frames for our guidance. Overall, we can choose between the Simple and the Perfect, in the PAST time compass. We are about to think on talking about feelings and minds. Chantelle’s first book tells about a girl’s language of the heart. Art Veltall is thinking about a job change. Contending his mother-in-law yet resembles trying verbally to captivate a moving rock …
Grammar exercises can "buy" us some luck at tests and exams — here we have some more of our grammar "good luck boutique", and good American does not have to be grave serious. More→
Isolated word form, whether auditory or visual, is not enough to convey language information. We can work our time frames only in context.
Our brains can work with verbal paths as well as visualization. It does not mean we have to stay with the words or visuals, especially forever. These are just to help. Importantly, without knowing where we are about faculties, activities, or states, we could be only repeating formulas after other people.
We can envision our grammar journey as traveling in an abstract dimension. However, we can think about the Cartesian coordinates, just as in our natural, three-dimensional realities.
