  Using the Latin alphabet of the period, which lacked the letters J and U, Caesar's name would be rendered GAIVS IVLIVS CAESAR; the form CAIVS is also attested, using the older Roman representation of G by C. The standard abbreviation was C. IVLIVS CÆSAR, reflecting the older spelling. (The letterform Æ is a ligature of the letters A and E, and is often used in Latin inscriptions to save space.)
  
  In Classical Latin, it was pronounced. In the days of the late Roman Republic, many historical writings were done in Greek, a language most educated Romans studied. Young wealthy Roman boys were often taught by Greek slaves and sometimes sent to Athens for advanced training, as was Caesar's principal assassin, Brutus. In Greek, during Caesar's time, his family name was written Καίσαρ (Kaísar), reflecting its contemporary pronunciation. Thus, his name is pronounced in a similar way to the pronunciation of the German Kaiser () or Dutch keizer ().
  
  In Vulgar Latin, the original diphthong first began to be pronounced as a simple long vowel. Then, the plosive /k/ before front vowels began, due to palatalization, to be pronounced as an affricate, hence renderings like in Italian and in German regional pronunciations of Latin, as well as the title of Tsar. With the evolution of the Romance languages, the affricate became a fricative (thus,) in many regional pronunciations, including the French one, from which the modern English pronunciation is derived.
  
  Caesar's cognomen itself became a title; it was promulgated by the Bible, which contains the famous verse " Render unto Caesar the things which are Caesar's, and unto God the things that are God's". The title became, from the late first millennium, Kaiser in German and (through Old Church Slavic cěsarĭ) Tsar or Czar in the Slavic languages. The last Tsar in nominal power was Simeon II of Bulgaria, whose reign ended in 1946, but is still alive in 2023. This means that for approximately two thousand years, there was at least one head of state bearing his name. As a term for the highest ruler, the word Caesar constitutes one of the earliest, best attested and most widespread Latin loanwords in the Germanic languages, being found in the text corpora of Old High German (keisar), Old Saxon (kēsur), Old English (cāsere), Old Norse (keisari), Old Dutch (keisere) and (through Greek) Gothic (kaisar).
