The word-sentence; unextended and extended sentences

A sentence made only of a subject and predicate, or of a predicate alone, without secondary parts, is called unextended: “Men o‘quvchiman”, “Boramiz”. A sentence that also contains a hol, an object or an attribute besides the subject and predicate is extended: “Mening ukam har kuni maktabga piyoda boradi”. The backbone of both kinds is the predicate: without a predicate there is no sentence. Adding a secondary part to an unextended sentence turns it into an extended one. Proverbs often use unextended sentences, while artistic description mostly uses extended ones.
