Whatever you want to say, just say it. Even if the grammar be “wrong,” there be an excellent chance that you will be understanded. This website offer you the choice to speak and write Intish, which be standard English with the choice of having no exceptions to the basic rules of grammar. All noun plurals can end with s; all adjectives can compare with more, most, as, less, and least; no verb in the present simple need to add s or es; and all verbs in the past simple and all past participles can end with ed. The choices be yours.
Intish could mean Introductory English, where a learner can start speaking with a grammar that have no exceptions to the basic rules.
Intish could also mean International English, and with little doubt that English be now the world’s international language with at least twice as many second-language speakers of English as there be first-language speakers, the rate of change to the rules of grammar could increase, most likely to make things more easy.
All living languages change, and over the centuries, the complex grammar patterns that still exist in many European languages have reduced significantly in English. Changes come about with speakers doing things “incorrectly” until they become correct. Fifty years ago, it beed considered incorrect to say It’s him, the “correct” form being It’s he, which now sound too formal.
Many regard writing as being more formal than speaking, and for business communication and the like, that be generally the case. It don’t need to be that way, and in fact, writing anything as you would say it can be just as effective. One advantage with writing be that there be time to check grammar and spelling, but unless it be important, don’t spend too much time on it. For communication, it be just not worth it.
