Intransitive case

If I understand question it is about Language and the way verbs work. To start most languages have a grammar based on SvO, or subject, verb object, or, again who or what does which to whom or what, which is grounded in the idea that whatever happens somebody or something makes it happen, taking anywhere as a starting point, since if we ask that about the universe as a whole it turns into who or what created it, if it has an origin, as in the Big Bang, say, or goes on all the time as a continuous Universe, the latest being what Fred Hoyle has to say about this.

Languages can and do use the order of SvO, VOs,OVs and so on any way around but for that language the order is fixed so that in order to use an OvS in an SvO system, we make it into the passive, as in 'Johnny eats an appple' active or "Johnny was eaten by an apple", passive or inversed. In the case of verbs it follows that the subject can do things to another thing or object, as above which is called transitive for a transfer of the action or energy, to something it uses, intransitive when there is no such transfer, as in 'I ride a horse' and reflexive of "I dress myself" when the action is done to the subject itself, like "Trees grow" where there is no need to add an object.

Although grammar is taught as a set of rules, it is a logical analysis of a "whodunnit". if we cannot find a whodunnit we tend to get puzzled. Language does not describe reality. It is ONEof many orderly ways to talk and think ABOUT it, so other people can break it down again into how they think about such things, which makes it a mind to mind code. It is forerever incomplete because something or somebody will show or find a twist nobody else thought of or did not happen before. For the three instances of a "case" with verb it comes as A <-> B or bidirectional which breaks down into A does it to B, or Not or again A does it to itself as in "the bloom blooms bloomingly" which shows any word can be a verb. noun, adjective and so on. If we cannot find a Subject as originating an action we get puzzled. This happens when we mix abstractions with concrete objects and actions as in "time flies" meaning do I get a stopwatch, donate time with wings, called personification, or give myself wings so I can watch time do it and other such variations, as for "I ride a Horse" who does the riding horse or me? I steer the horse, but horse does all the work. Or again, as a road sign In Orakei, New Zealand which is geologcially active, 'Steam drifts across Road' which everybody understands, we can argue forever whether it is Steamdrifts, making it a noun, or drifts as a verb. A clearer way to put it could be "expect steam drifts on road" or watch out for... but whoever made the road sign did it in the least words needed.

A totally different way to look at all this comes as thinking about it as active energy flows all dancing together and as Ishmael puts it in "Moby Dick": "Thus the universal thump is passed along". So here as anyhwere a simple question can open several cans of worms in many ways.
