yüksekliidir

Yüksekliidir is a Turkish verb form that appears in the third‑person singular present indicative of the verb *yüksekli-*, which itself is derived from the adjective *yüksek* meaning “high” or “tall.” The full conjugation of the verb trend is *yüksekli‑den + edir*, a compound of the adjective stem and the copulative suffix *‑li* that attaches noun‑like adjectives to verbs to express a state. The resulting form literally translates to “is high” or “is tall.” It is used to describe static, inherent characteristics of a noun, typically in an objective, factual context.

The word plays an important role in Turkish grammar for demonstrating the copular construction of adjective‑derived verbs. Because it is a neutral descriptive verb, it is frequently found in scientific descriptions, encyclopedic entries, and other formal writing to convey measurements or spatial relationships. For example, one might write “Dağın yüksekliidir 3,200 metre,” meaning “The mountain’s height is 3,200 meters.” The form is also a key example in teaching Turkish verb conjugation, especially when teaching how adjectives can be turned into declarative verbs with the addition of the suffix *‑li*.

Phonologically, the word is pronounced /yʏˈkeʃliːðiɾ/. In contemporary Turkish literature and journalism it appears rarely as a standalone phrase, because most descriptions favor more explicit noun phrases (e.g., *yükseklik*) or adjectives (e.g., *yüksek*). Nonetheless, it remains a standard grammatical form taught in language courses to illustrate the flexibility of Turkish verb derivation from adjectives.
