Transliteration
Conversion of a text from one script to another
Transliteration is a type of conversion of a text from one script to another that involves swapping letters (thus trans- + liter-) in predictable ways, such as Greek ⟨α⟩ → ⟨a⟩ and ⟨χ⟩ → the digraph ⟨ch⟩, Cyrillic ⟨д⟩ → ⟨d⟩, Armenian ⟨ն⟩ → ⟨n⟩ or Latin ⟨æ⟩ → ⟨ae⟩.
