Editing Khmer script (section)

=== Supplementary consonants ===
The Khmer writing system includes supplementary consonants, used in certain [[loanword]]s, particularly from [[French language|French]] and [[Thai language|Thai]]. These mostly represent sounds which do not occur in native words, or for which the native letters are restricted to one of the two vowel series. Most of them are [[digraph (orthography)|digraph]]s, formed by stacking a subscript under the letter {{lang|km|ហ}} {{transliteration|km|hâ}}, with an additional ''treisăpt'' [[#Diacritics|diacritic]] if required to change the inherent vowel to ''ô''. The character for ''pâ'', however, is formed by placing the ''musĕkâtônd'' ("mouse teeth") diacritic over the character {{lang|km|ប}} {{transliteration|km|bâ}}.
