RULES FOR THE SPELLING OF GEOGRAPHICAL NAMES FOR BRITISH OFFICIAL USE.

(Termed the R.G.S. II system.)

1. The spelling of every place-name in an independent country or self-governing dominion using the Latin alphabet[20] shall be that adopted by the country or dominion, except in the case in which certain important localities have also, in addition to the official name, another customary name, notably different, in which case the name customary in British use (i.e., “conventional”) may be adopted (e.g., Geneva, Warsaw, etc., for Genève, Warszawa, etc.).

2. The spelling of such place-names in colonial possessions as belong to languages coming under Rule (1) will be spelt in accordance with that rule.

3. The accents and diacritical marks in official use by the above countries will be retained. Wherever it appears desirable, the pronunciation will be shown by giving the name as transliterated on the system below.

4. All other place-names throughout the world will (with the exception of “Conventional” names and some others) be spelled in general accordance with the following system, which is based upon, and differs only slightly from, the system long used by the Royal Geographical Society, from which are derived the War Office system, 1906,[21] and the system of the Intelligence Division, Naval Staff, 1917.[22]

The broad features of this system are—

(a) That vowels are pronounced as in Italian and consonants as in English;

(b) That every letter is pronounced, and no redundant letters are used.

The system aims at giving a close approximation to the local pronunciation; but it is recognised that in some languages, notably Russian, Greek, and Arabic, the necessity for letter-for-letter transliteration often renders this impossible.

Table of Spelling and Pronunciation R.G.S. II.

kh	Hard aspirated guttural, as in the Scottish loch (not as in lock)	Khan, Sebkha.
l[†]	} As in English.
m

z	As in gaze, not as in azure.
zh	As the s in treasure, the z in azure, or the French j in je; but for the sound in Russian, Bulgarian, and Chinese use j (vide note above under j)	Zhob, Azhdaha.
Notes.
	The doubling of a vowel or a consonant is only necessary when there is a distinct repetition of the single sound, and should otherwise be avoided	Nuulua, Loolmalasin, Jidda, Muhammad.
	Accents should not generally be employed; but in order to indicate or emphasise the stress, an acute accent may be used	Saráwak, Qántara, Tong-atábu, Paraná.
	A long or short mark over a vowel (e.g. ā, ŏ) should only be used (and that sparingly) when without it there would be danger of mispronunciation	Kūt, Hashīn, Angŏra.
	Hyphens will not be used except to indicate pronunciation, and with the Persian izafat, -i-	Mus-hil; Pusht-i-Kuh.

[*] The long and short symbols given in this column are merely for explanation, not for use.

[†] See note at end on Liquid sounds.

[‡] Pronounced differently in Greek: see ‘Alphabets of Foreign Languages transcribed into English according to the R.G.S. II system’ (to be published in the R.G.S. Technical Series).

[§] This decision has been arrived at chiefly owing to the large number of English (and French) maps of these countries in which the zh sound appears as j.

[¶] The true Italian ō is broader than this: almost as in broth.

Inverted Comma and Apostrophe.—The inverted comma ʿ is employed only to represent the Arabic ʿain, ع, and the Hebrew ʿayin, ע. The apostrophe ’ in foreign words indicates a liquid sound. (See below.)

Liquid Sounds.—The occasional “liquid” or “palatalised” sound of d, l, n, r, t, etc. (as in d’you, lure, new, clarion, tune), is as a rule sufficiently represented by a following y; where, however, owing to a following consonant, or to the letter in question coming at the end of a word, the y is inapplicable, the liquid sound will be represented by an apostrophe, thus: d’, l’, n’, r’, t’, etc.

The “Neutral Vowel”.—The “indeterminate” or “neutral” vowel sound (er), i.e. the sound of a in marine, e in often, i in stir, io in nation, o in connect, ou in curious, u in difficult, etc., e in French je, or the often unwritten vowel (َ Fat-ha) in Arabic, etc., is represented as a rule by a: as in Basra, Hawiya; but sometimes by e, when the sound approximates more to e than to a: as Meshed, El Gezira.

(In any guide to pronunciation issued by the Permanent Committee on Geographical Names, the “neutral vowel” is represented generally by the italic e: occasionally also by italic a or u.)

This sound must not be confused with e-mute, where the e is not sounded at all: as in Abbeville.
