Most Klingon vocabulary consists of nouns and verbs. However, there are other words that don't fit neatly into these two categories. Klingon grammarians group these miscellaneous words under the category called chuvmey, meaning "leftovers" or "miscellaneous words." While originally a convenience, these chuvmey can still be sorted into various subgroups based on their grammatical functions:

Pronouns

Independent pronouns like jIH ("I"), SoH ("you"), and ghaH ("he/she") function similarly to nouns or verbs but are grammatically distinct enough to fall into the chuvmey category. They can serve as stand-alone words for clarity or emphasis.

Numbers

Klingon numbers, such as wa' ("one"), cha' ("two"), and wej ("three"), are included within chuvmey. They modify nouns directly, and their unique grammatical usage separates them from other types of words.

Conjunctions

Words used to link nouns, verbs, clauses, or sentences—such as 'ej ("and"), qoj ("or"), and 'ach ("but")—fall under chuvmey. These words clarify relationships between different parts of sentences.

Adverbials

Adverbial words modify or qualify verbs and sentences. Examples like nom ("quickly"), batlh ("with honor"), and not ("never") indicate the manner, frequency, or attitude related to the action of a verb.

Exclamations and Interjections

Short emotional expressions such as toH ("well!"), maj ("good!"), and wejpuH ("charming!") belong to chuvmey. These exclamations stand alone and convey strong feelings or reactions quickly and efficiently.

Names and Terms of Address

Proper names, titles, and terms used when addressing others directly—such as torgh ("Torg"), HoD ("Captain"), or joHwI' ("My Lord")—are considered chuvmey because they do not require additional grammatical suffixes or prefixes and primarily indicate identity or respect.

Words of Direct Address

When addressing someone directly within a sentence, Klingon places the addressed person's name or title separately. Such words, called "vocatives," form part of the chuvmey category due to their unique standalone grammatical usage:

• HoD, qaja'pu' – Captain, I have told you.
• torgh, HIghoS – Torg, come to me!

These chuvmey words—though termed "leftovers" by traditional Klingon grammar—are essential parts of speech. They provide clarity, detail, and subtlety, enhancing communication and nuance in the Klingon language.
