The website says there a three main tenses in English, the present, the past, and the future. The tense of a verb tells when a person did something or when something existed or happened.
This is trouble enough, we stop here. The trouble is italicized above.
Grammatical tenses are not clocks or chronicles, and they do not tell when; they do not give the date, hour, or other circumstance. The tenses also do not tell to choose if something existed OR happened.
If we look up Lexico for the word ■→OR, we may read it tells alternatives, synonyms, or afterthought.
For an ■→ALTERNATIVE, granny can tell from living experience that non-existent things don’t happen, and things that exist may never happen in our lives, so existence and happening are not ■→SYNONYMS, either. Football and baseball might be synonyms for things that happen and are no ■→AFTERTHOUGHT.
Let us see some more text from ■→LEXICO.
The present tense is also called the present simple or simple present. It’s mainly used in the following ways:
■ to describe things that are currently happening or that are currently or always the case;
■ to talk about something that exists or happens regularly;
■ to refer to a future situation in certain cases and in some subordinate clauses.
The present, past, or future are the grammatical time; they are not tenses. For the difference, feel welcome to have a look here:
Everyday language has phrases as a flow or passage of time, a course or current of events: we people happen to have such impressions about life and time. Let us imagine a river of time. There are word patterns to show in the river, and there are pods of time to surface with them. We need to use a pattern, for a pod to carry us through. ■→More
Further, we can go ■→WORDNET SYNSETS for words as currently or always.
■→CURRENT things can be modern or new; a current position could be the actual place something is; current events are those live or on-going; and a current report would be up-to-date or the latest.
Things that ■→ALWAYS happen can be constant, incessant, or perpetual, and we say something is always possible, if it can happen any time; if we say that something is always to be, we mean it is forever. The word sense does not belong with the PRESENT only.
WordNet is really good, tells about words a lot, and we are sure going to find all we need to work the text entire. In the end, we are going to have to come up with a conclusion and see if it works. We’d better be “down to earth” with this, for our skill really to work.
Words as always, currently, regularly, certain, or some are not verb forms. Let us think about a view to the verb form solely. The one here would be a view ON a ground.
Granny cannot put any conclusion in your head; feel welcome to read about ■→VERBS and try the idea here:
Human walking or other moving about needs place and time, yet it does not need anybody to describe, give rules or definitions. We can connect the grammatical aspect and basic ways we people orientate in physical space. More→
