Compiled by the UNGEGN Working Group on Romanization Systems
Version 2.2, January 2003


The United Nations recommended system was approved in 1972 (II/11) and amended in 1977 (III/12), based on a report prepared by D. N. Sharma. The tables and their corrections were published in volume II of the conference reports (Second United Nations Conference on the Standardization of Geographical Names. London, 10-31 May 1972. Vol. II. Technical papers. United Nations. New York 1974, pp. 149-150; Third United Nations Conference on the Standardization of Geographical Names. Athens, 17 August - 7 September 1977. Vol. II, Technical papers, pp. 393 etc.).

There is no evidence of the use of the system either in India or in international cartographic products.

Malayalam (Malayāḷam) uses an alphasyllabic script whereby each character represents a syllable rather than one sound. Vowels and diphthongs are marked in two ways: as independent characters (used syllable-initially) and in an abbreviated form, to denote vowels after consonants. The romanization table is unambiguous but now outdated because since the 1970's a new orthography has been introduced and the use of many character combinations and ligatures has been simplified. Nevertheless the user of the romanization table would have to recognize many ligatures not given in the original table. The system is mostly reversible but there exist some ambiguities in the romanization of vowels (independent vs. abbreviated characters) and consonants (ligatures vs. character sequences), particularly in the case of older orthography.


The romanization system below is based on the new orthography, with notes where appropriate on the older spelling. The table of ligatures has been added.

II. Abbreviated vowel characters (ട stands for any consonant character)

Many of the ligatures, especially those marked with the asterisk are thought to be obsolete since the introduction of the new spelling and have been replaced by a combination of two consonant characters, the first of which bears the ്‌ diacritic, e.g. പ്‌ന pna. However, the usage of ligatures in different sources varies greatly.

Other systems of romanization

For differences between the UN system and the ISO transliteration standard ISO 15919: 2001 see the section on the romanization of Hindi.

The State of Kerala seems to use a regular pattern for rendering their geographical names. At least the following correspondences may be noted:

 UN State of Kerala
 = zh
 sh = s
 t = th
 = t or d
