Tesvisio

Tesvisio, a Finnish word, is a relatively uncommon colloquialism for "televisio," the standard Finnish word for television. It is often used humorously or informally, sometimes to emphasize a perceived lower quality or older model of television. While "televisio" is the standard term used in formal settings, news broadcasts, and official publications, "tesvisio" might be heard in casual conversation, particularly among older generations. The difference in usage is similar to using a more slang-based or dialectal term for a common object, adding a layer of familiarity or perhaps mild disparagement. The origin of the "s" insertion is likely playful alteration of the original word, and doesn't hold any significant etymological meaning beyond this casual modification. It is not considered grammatically incorrect, but rather a stylistic or pragmatic choice.
