Questions & Answers about Tieto on tiedostossa.
Why do tieto and tiedosto look so similar?
They both share the same root. Tieto means information or knowledge. The suffix -sto is used to create words for collections of things, so tiedosto literally means a collection of information, which is the Finnish word for a computer file.
Why is the word for file tiedosto instead of tietosto with a T?
When building new words, Finnish often attaches suffixes to the weak stem of a word. The weak stem of tieto is tiedo- (the T changes to D because of consonant gradation). Adding the -sto collection suffix to that weak stem gives us tiedosto.
Are there other common words that use the -sto suffix like tiedosto does?
Yes, it is a very common way to build vocabulary at this level! It usually means a collection of things. For example, kirja (book) becomes kirjasto (library), and sana (word) becomes sanasto (vocabulary or glossary).
Why do we use the -ssa ending for a computer file?
The ending -ssa means in or inside. Just like in English, Finnish treats digital files, folders, and the internet as containers or spaces, so you say the information is physically inside the file (tiedostossa).
