As a heads up, this is a good sort of question for the Short Answers to Simple Questions thread, as this doesn't really require a lengthy answer.

• King of Ḫattuša / Ḫatti – LUGAL KUR ^URU Ḫa-at-ti (𒈗 𒆳 𒌷 𒄩 𒀜 𒋾)

• Great King – LUGAL.GAL (𒈗 𒃲)

• Man of Kuššara – LÚ ^URU ku-uš-šar (𒇽 𒌷 𒆪 𒍑 𒊬)

• Labarna – la-ba-ar-na (𒆷 𒁀 𒅈 𒈾), ta-ba-ar-na (𒋫 𒁀 𒅈 𒈾)

LUGAL, GAL, KUR, URU, and LÚ are not Hittite but rather Sumerian, which is why they're capitalized in transliterations. Hittite scribes often preferred to use Sumerian words as a shorthand for common words since most Sumerian words require only one or two signs. Sumerian words used as substitutes for Hittite words are called "Sumerograms." Occasionally Hittite scribes added a phonetic ending to a Sumerogram that indicated it was to be read in a particular language. These signs are known as "phonetic complements." For example, LUGAL-uš was read aloud as Hittite ḫaššuš as opposed to, say, Akkadian šarru.

URU is in superscript because it is what is known as a determinative (or classifier), an unvocalized sign that gives you information about that word. É (building/structure), GIŠ (wooden object), MUŠEN (bird), and ÍD (river) are a few other examples of determinatives.

The Hittite equivalents are as follows:

• LUGAL = ḫaššu-

• GAL = šalli-

• KUR = utnē

• URU = ḫappiriya‐

• LÚ = antuḫša‐
