Mikä oli Suomen yleisin sukunimi 2018?
Korhonen is a surname originating in Finland, where it is the first most common surname. 
It has no transparent meaning in modern Finnish, but is likely to have been derived from the mostly archaic word 'korho'. In some dialects, this word is used to mean a person of poor hearing or a numb-witted person. On the other hand, professor Alfred Salmela suggested in 1970 that the word 'korho' is a loan from the Baltics and has meant "old, village elder or chief". It still reported to carry a meaning of "proud, rich and boastful" in the southern parts of Finnish Lapland.
