corpus as a whole) are linguistically more innovative. Transliteration and transcription Transliteration of Pahlavi script In view of the many ambiguities of the Pahlavi script, even its transliteration does not usually limit itself to rendering merely the letters as written; rather, letters are usually transliterated in accordance with their origin regardless of the coinciding forms: thus, even though Book Pahlavi has the same letter shapes for original n, w and r, for original ʾ and ḥ and for original d, g and y, besides having some ligatures that coincide in shape with certain individual letters, these are all transliterated differently. For instance, the spelling of gōspand 'domestic animal' is transliterated gwspnd in spite of the fact that the w and n have the same graphic appearance. Furthermore, letters used as part of Aramaic heterograms and not intended to be interpreted phonetically are written in capitals: thus the heterogram for the word ān is rendered ZK, whereas its phonetic spelling is transliterated as ʾn' (the final vertical line reflects the so-called 'otiose' stroke, see below). Finally, there is a convention of representing 'distorted/corrupt' letters, which 'should' have appeared in a different shape from a historical point of view, by under- or overlining them: e.g. the heterogram for andar 'in' is transliterated BYN, since it corresponds to Aramaic byn, but the sign that 'should' have been b actually looks like a g. Within Arameograms, scholars have traditionally used the standard Semitological designations of the Aramaic (and generally Semitic) letters, and these include a large number of diacritics and special signs expressing the different Semitic phonemes, which were not distinguished in Middle Persian. In order to reduce the need for these, a different system was introduced by D. N. McKenzie, which dispenses with diacritics as much as possible, often replacing them with vowel letters: A for ʾ, O for ʿ, E for H, H for Ḥ, C for Ṣ, for example ORHYA for ʿRḤYʾ (bay 'god, majesty, lord'). For ''ṭ'', which still occurs in heterograms in Inscriptional Pahlavi, Θ may be used. Within Iranian words, however, both systems use c for original Aramaic ṣ and h for original Aramaic ḥ, in accordance with their Iranian pronunciation (see below). The letter l, when modified with a special horizontal stroke that shows that the pronunciation is /l/ and not /r/, is rendered in the McKenzie system as ɫ. The traditional system continues to be used
