ラーオ語
Some consonant clusters were maintained in the Lao language for some vocabulary, mostly of Sanskrit and Pali derivation and used in royalty or religious settings, but the most recent spelling reforms in the Lao language removed most of them. The Thai language has preserved all of them, and when Isan is written in Thai, cognates of Thai words are spelled as if they are pronounced in Thai, with consonant clusters that are usually not pronounced in Isan except some religious and technical terms.
