The International Linguistics
Linguistics
Linguistics is the scientific study of human language. Linguistics can be broadly broken into three categories or subfields of study: language form, language meaning, and language in context....

Olympiad (IOL) is one of the newest in a group of twelve International Science Olympiad

International Science Olympiad

The International Science Olympiads are a group of worldwide annual competitions in various areas of science. The competitions are designed for the 4-6 best high school students from each participating country selected through internal National Science Olympiads, with the exception of the IOL,...

s. The setup differs from other science olympiads, in that the program contains both individual and team contests. The abbreviation IOL is deliberately chosen not to correspond to the name of the organization in any particular language, and member organizations are free to choose for themselves how to designate the competition in their own language.

This olympiad furthers the fields of mathematical, theoretical, and descriptive linguistics. Like all science olympiads, its problems are translated and completed in several languages and as such must be written free of any native language constraints. In practice, this is often difficult and competitors may gain some advantage if they are familiar with one or more of the language groups which are the subject of some of the assignments. However, the most helpful ability is analytic and deductive thinking, as all solutions must include clear reasoning and justification (as in solving mathematical problems).

The individual contest consists of 5 problems which must be solved in 6 hours. The problems cover the main fields of theoretical, mathematical and applied linguistics – phonetics

Phonetics

Phonetics is a branch of linguistics that comprises the study of the sounds of human speech, or—in the case of sign languages—the equivalent aspects of sign. It is concerned with the physical properties of speech sounds or signs : their physiological production, acoustic properties, auditory...

, semantics

Semantics

Semantics is the study of meaning. It focuses on the relation between signifiers, such as words, phrases, signs and symbols, and what they stand for, their denotata....

, etc.

Since the 2nd IOL, the team contest has consisted of one extremely difficult and time-consuming problem. Teams, which generally consist of 4 students, are given 3–4 hours to solve this problem.
