Lisalauseid

Lisalauseid is a term used in linguistic description to refer to clauses that attach to a main clause to provide supplementary information. They express details such as description, clarification, or commentator material that is not essential to the core proposition of the main clause. Lisalauseid can be realized in several ways across languages, most commonly as non-restrictive relative clauses, appositive clauses, or parenthetical clauses. In written text they are typically set off by commas, dashes, or parentheses, and their presence can affect tone and emphasis.

In usage, lisalauseid help expand the scene or participant information without altering the truth conditions of the main clause. They may be introduced by relative pronouns, conjunctions, or punctuation. Similar concepts in other languages include non-restrictive clauses or supplement clauses.

Examples:

- The museum opened yesterday, which attracted many visitors.

- Muuseum avati eile, mis tõi palju külastajaid.

- The author, who has won several prizes, spoke at the conference.

- The plan, if approved, will go into effect next year.

Relation to other terms: Lisalauseid overlap with relative clauses, appositive clauses, and digressive insertions. They are distinguished from essential content clauses that limit or define a noun or assert a factual claim. Overall, lisalauseid function as a linguistic device for adding background or commentary without changing the core message of the main clause.
