Tenseless languages
Language that do not possess the grammatical category of “tense”, although obviously, they can communicate about past or future situations, but they do it resorting to adverbs (earlier, yesterday, tomorrow), the context (pragmatics), but mostly aspect markers, that show how a situation relates to the timeline (perfective, continuous, etc.) or modal markers (obligation, need, orders, hipothesis, etc.)
Tenseless languages are mostly analytic/isolating, but some are not. They occur mainly in East and Southeast Asia (Sino-Tibetan, Austroasiatic, Austronesian, Kra-Dai, Hmong-Mien), Oceania, Dyirbal (in NE Australia), Malagasy, Yoruba, Igbo, Hausa, Ewe, Fon and many Mande languages of Western Africa, most creole languages, Guarani, Mayan languages, Hopi, some Uto-Aztecan languages, and Greenlandic and other Inuit dialects.
