BGN/PCGN romanization of Russian in the context of "Translit."

Transliteration is the attempt to represent the text of one language in the writing system of another. For instance, for the Greek term ⟨Ελληνική Δημοκρατία⟩, which is usually translated as 'Hellenic Republic', the usual transliteration into the Latin script (romanization) is ⟨Hellēnikḗ Dēmokratía⟩; and the Russian term ⟨Российская Республика⟩, which is usually translated as 'Russian Republic', can be transliterated either as ⟨Rossiyskaya Respublika⟩ or alternatively as ⟨Rossijskaja Respublika⟩.

Transliteration is the process of representing or intending to represent a word, phrase, or text in a different script or writing system. Transliterations are designed to convey the pronunciation of the original word in a different script, allowing readers or speakers of that script to approximate the sounds and pronunciation of the original word. Transliterations do not change the pronunciation of the word. Thus, in the Greek above example, ⟨λλ⟩ is transliterated ⟨ll⟩ though it is pronounced exactly the same way as [l], or the Greek letters, ⟨λλ⟩. ⟨Δ⟩ is transliterated ⟨D⟩ though pronounced as [ð], and ⟨η⟩ is transliterated ⟨ē⟩, though it is pronounced [i] (exactly like ⟨ι⟩) and is not long.
