What is the HKLO?

Hong Kong Linguistics Olympiad is the accredited competition to allow pre-university students to participate in the international linguistics competitions (International Linguistics Olympiad and Asia Pacific Linguistics Olympiad). The linguistics Olympiad consists of solving linguistic puzzles which require only logical ability, patient work and the willingness to accept challenges. No prior knowledge of linguistics or second languages is required. Students can learn more about the knowledge of world languages and improve their abilities of observation, logic and awareness of diversity while solving problems involving language data. Everyone is welcome to give it a try and explore the wondrous realm of language and experience its gems. The working language for HKLO is English. Participants who are eligible for linguistic Olympiads in other nations/regions (in addition to Hong Kong) cannot compete in multiple contests each year.

Targeted participants are from Form 1 to Form 6 students in Hong Kong secondary schools. If you have any questions, please don’t hesitate to contact us at This email address is being protected from spambots. You need JavaScript enabled to view it.
