# tosi
## Finnish
### Etymology

From Proto-Finnic *toci (compare Estonian tõsi), from Proto-Uralic *čoďe (compare Eastern Khanty [script needed] (čăjǝ), Northern Mansi [script needed] (sōĺ)).

### Pronunciation

* IPA: /ˈtosi/, [ˈt̪o̞s̠i]
* Rhymes: -osi
* Hyphenation: to‧si

### Adjective

tosi (comparative todempi, superlative tosin)
* true
* (in compounds) real, serious, real-life
    tositarina ― real-life story

#### Usage notes

* (true): When used predicatively, the adjective is always either in the partitive singular, or somewhat less commonly in the nominative singular:
    Tämä on totta! / Tämä on tosi!This is true! / I mean it/business!
* (real, serious): Used as an attribute or as a modifier in a compound term.
    ryhtyä tositoimiin ― to take serious action
    tosiasia ― fact
* The comparative form is uncommon and the superlative form is rare.
* Outside of more formal and technical language (e.g. in logic), in everyday speech, all other forms than the nominative and partitive singular are uncommon, outside of their use as adverbs:
** näyttää toteen (“to prove”)
** olla totta (“to be true”)
** ottaa todesta (“to take seriously; to take for granted”)
** todella (“really, very”)
** toden teolla (“really”)
** toden totta (“indeed, sure enough”)
** toden tullen (“if push comes to shove, if things really get tough”)
** tosiaan (“indeed, really”)
** tosin (“granted, although, (given that) it is true that”)
    Hän on tosin viisaampi. ― True, s/he is wiser.
** tosissaan (“serious(ly)”)
