olettaa

ole- (“to be, exist”) +‎ -ttaa (causative aspect) — therefore, literally “to cause to exist”. Coined by Finnish physician and translator Wolmar Schildt in 1847. In the folk language, meanings like "to order, command" can be found in Western Finnish and "to put on airs" in Savonia.

• IPA^(key): /ˈoletːɑːˣ/,
• Rhymes: -oletːɑː
• Hyphenation^(key): olet‧taa

olettaa (transitive)

1. to assume, suppose, presuppose
2. (logic) to premise, postulate
3. to hypothesize (in empiric research)

• olettaa has a slight sense of believing something with thoughts that it could not even be untrue. otaksua has, on the other hand, a slight sense that the speaker believes something, but still leaves some room for other possibilities about the state of affairs. otaksua also has a more formal nuance than olettaa and thus it is often translated into English as "presume".
