Questions & Answers about Uusi olettamus on yhtä huono kuin vanha.
How is the noun olettamus formed from a verb?
It is derived from the verb olettaa (to assume). By dropping the final vowel and adding the suffix -mus, it forms an abstract noun representing the result of that action, which gives us olettamus (an assumption).
I have also seen the word oletus for assumption. What is the difference between oletus and olettamus?
They are very similar and both come from olettaa. Oletus is the standard, everyday word for assumption, and is also used for default settings in tech. Olettamus carries a slightly heavier, more formal or scientific tone, often translating closer to a formal presumption or hypothesis.
How does the yhtä ... kuin structure work here?
This is the standard Finnish way to express equality, meaning 'as [adjective] as'. The word yhtä is technically the partitive form of yksi (one), but here it acts as an adverb meaning 'equally'. So yhtä huono kuin literally means 'equally bad as'.
The English translation says 'the old one', but the Finnish sentence just ends with vanha. Why isn't there a translation for 'one'?
Finnish does not use a dummy pronoun like 'one' to replace a previously mentioned noun. When the context is clear, the adjective simply stands alone. Using a word like yksi here would sound completely unnatural.
