Think you are to write up examples, let us say, only for irregular verbs, but in all grammatical tenses, the twelve at least.
You’d be making yourself some wallpaper, it is so much to write, and you wouldn’t be done in a day. Hi, I’m John. In this vision, I am not even half way through, after a week of writing.
Some nice wallpaper it could be, full of color, and bright, but it comes natural to think about living without having to carry scrolls, except when you want to redecorate.
I haven’t been carrying scrolls around, though I can think what I know for sure.
It is absolutely certain that if we take to reckoning about all the rules and definitions we get about Reported Speech, Future in the Past, or Unreal Past, we are more than likely to get mixed up on any particular occasion we speak.
It is just as invariably true that even if we get mixed up completely, in reality, there is still going to be just one present, one past, and one future. Or, there’s no reason to make things more complicated.
Time flows. The present becomes the past, and the future becomes the present. The past remains the past, but this is what never has changed in human experience, and grammar does not need complexity over this.
We could be looking up clouds, but we people like to have reference. Let us set out three extents, for the present, past, and future.
We need light, to learn, and there is light in our fields. Our PAST field can be as with a setting sun. We may forget the detail in matters we have not studied in a long time, yet there is shine enough to return to them.
We cannot have memories of the FUTURE, but we are capable of planning our study. Our field for the FUTURE can be as with sunrise.
It is our PRESENT we have the most ability to shape. We can symbolize the PRESENT as shiny daylight.
The pictures might look a bit “girly”, but the thing comes from a girl. I even thought about making “manly” illustrations, but the pictures would’ve been just darker or grayscale, and I thought it would’ve been bias, you know, like males don’t make out the →chromatic, so things stay the way they’ve been.
It is common sense to talk “on a ground” rather than “groundless”→ nonsense, and we can have a symbolic picture for such a ground. Things are easier when you visualize.
We have the same ground for the past, present, or future, whatever Unreal Past or Future in the Past there would be in life to cope with.
We can tell what generally there is or is not, ON our ground. For example, I think. Grammar calls it the Simple.
We can tell it is just some extent of our ground we are speaking about. In reality, matters are very similar when we are IN an area, for example, I am thinking. Grammars call it the Progressive or Continuous.
Our ground allows viewing matters TO a point in time, too. For example, I have thought. This does not mean we have to change and stop thinking what we have thought. Grammars name it the Perfect.
We can reckon how we have viewed things from an area. The two views combined, TO and IN, we reckon as AT a point. For example, I have been thinking. It is the Perfect Progressive.
We don’t need to write up any wallpaper anymore. We can reckon on a ground and four ways to view matters and life we picture with the words ON, IN, TO, and AT.
The words ON, IN, TO, and AT are variables. We choose one of the set.
The word “variable” is sometimes used in experiments, but in another sense. It tells what changes. Our ON, IN, TO, and AT work always the same. Our sense for the word is “one of a set of values”, if you compare →Merriam-Webster.
We’re only not into quantity for those, as there’s nothing really to calculate about the Simple, Progressive, Perfect, or Perfect Progressive, in human use.
Our gumption set is not an experiment. You’d probably try something more classic for experiments, to get those other variables, that is, changing ideas.
You could say, OK, but if we tell what might be, it is not so clear if the ground refers to the past, present, or future.
We can resolve on this with something we have in reality, too.
If you have ever hiked, you know there are trails, and they have arrow signs.
We could say the FUTURE brings the matters that are BEFORE us, and PAST things are those BEHIND us. In our minds, we could look forward or back to events from where we always are, our PRESENT.
The Simple Aspect can have a symbol as a plain arrow.
The Progressive can have a dot, for being in a spot, an area.
The Perfect Aspect has showed our way to a place or time. We can add an arrow or spearhead to our simple dart.
The Perfect Progressive combines the Perfect and the Progressive.
In context, we know if the talk is about the past, present, or future. It is enough we think about the target grammatical time.
Tomorrow, we might go hiking.
We might go hiking today.
