 The Khmer script includes the symbol ៗ, which indicates that the preceding word or phrase is to be repeated.As is typical of most East Asian languages, Khmer verbs do not inflect at all; tense and aspect can be expressed using particles (such as កំពុង , placed before a verb to express continuous aspect) and adverbs (such as "yesterday", "earlier", "tomorrow"), or may be understood from context.Serial verb construction is quite common.
