lukio

Coined by Finnish linguist and author Reinhold von Becker in 1836, most likely as luk- (“to read, study”) +‎ -io, However, Latin Lycēum (from Ancient Greek Λύκειον (Lúkeion), compare English lyceum, Finnish lyseo) is possibly also related, and the possibility of the word being a phono-semantic matching cannot be ruled out.

lukio

1. a usually three-year (upper) secondary school in the Finnish school system (usually for students aged 15/16–18) that prepares the students for academic studies at a university; corresponds to the gymnasium (Europe), senior high school (US) and high school in some other places

• In the current Finnish school system lukio is preceded by nine years of peruskoulu. Until the 1970s there were four years of kansakoulu followed by five years of keskikoulu. keskikoulu and lukio were together called oppikoulu. Those who did not pass the exam for oppikoulu continued in kansakoulu and kansalaiskoulu for another four to five years.
