QUASI-ADJECTIVES

Along with "true adjectives," LPQR also contains a group of words called "quasi-adjectives," QUASI-ADJECTIVǏ.These lack the basic grammatical characteristics of adjectives, do not end in the letter combinations "-ij," "-ǐj," or "-oj."

While each “true adjective” has three word forms (a long form, a short form, and a comparative), quasi-adjectives have only one word form.

Like real adjectives, quasi-adjectives are not declined and do not change endings depending on gender and number.

Like true adjectives, they can act as either an attribute or a predicate in sentences. As attributes, they appear after the word they define. It's recommended to connect such attributes to the word they define with a hyphen.

Most quasi-adjectives are borrowed from Latin, Greek, and other European languages, but not from Russian. They are used primarily in scientific, technical, educational, political, and medical texts.
In everyday speech, only one quasi-adjective is more or less widely used: "elektri" (electric).
