Greek alphabet

There are many different methods of rendering Greek text or Greek names in the Latin script. The form in which classical Greek names are conventionally rendered in English goes back to the way Greek loanwords were incorporated into Latin in antiquity. In this system, ⟨κ⟩ is replaced with ⟨c⟩, the diphthongs ⟨αι⟩ and ⟨οι⟩ are rendered as ⟨ae⟩ and ⟨oe⟩ (or ⟨æ,œ⟩) respectively; and ⟨ει⟩ and ⟨ου⟩ are simplified to ⟨i⟩ and ⟨u⟩ respectively. In modern scholarly transliteration of Ancient Greek, ⟨κ⟩ will usually be rendered as ⟨k⟩, and the vowel combinations ⟨αι, οι, ει, ου⟩ as ⟨ai, oi, ei, ou⟩ respectively. The letters ⟨θ⟩ and ⟨φ⟩ are generally rendered as ⟨th⟩ and ⟨ph⟩; ⟨χ⟩ as either ⟨ch⟩ or ⟨kh⟩; and word-initial ⟨ρ⟩ as ⟨rh⟩.
