for one hundred million, and ("one thousand million") to mean one billion. Different Cambodian dialects may also employ different base number constructions to form greater numbers above one thousand. A few of the such can be observed in the following table: Counting fruits Reminiscent of the standard base 20 Angkorian Khmer numbers, the modern Khmer language also possesses separate words used to count fruits, not unlike how English uses words such as a "dozen" for counting items such as eggs. Sanskrit and Pali influence As a result of prolonged literary influence from both the Sanskrit and Pali languages, Khmer may occasionally use borrowed words for counting. Generally speaking, asides a few exceptions such as the numbers for 0 and 100 for which the Khmer language has no equivalent, they are more often restricted to literary, religious, and historical texts than they are used in day to day conversations. One reason for the decline of these numbers is that a Khmer nationalism movement, which emerged in the 1960s, attempted to remove all words of Sanskrit and Pali origin. The Khmer Rouge also attempted to cleanse the language by removing all words which were considered politically incorrect. Ordinal numbers Khmer ordinal numbers are formed by placing the word in front of a cardinal number. This is similar to the use of ที่ thi in Thai, and thứ (from Chinese 第) in Vietnamese. Angkorian numbers It is generally assumed that the Angkorian and pre-Angkorian numbers also represented a dual base (quinquavigesimal) system, with both base 5 and base 20 in use. Unlike modern Khmer, the decimal system was highly limited, with both the numbers for ten and one hundred being borrowed from the Chinese and Sanskrit languages respectively. Angkorian Khmer also used Sanskrit numbers for recording dates, sometimes mixing them with Khmer originals, a practice which has persisted until the last century. The numbers for twenty, forty, and four hundred may be followed by multiplying numbers, with additional digits added on at the end, so that 27 is constructed as twenty-one-seven, or 20×1+7. Proto-Khmer numbers Proto-Khmer is the hypothetical ancestor of the modern Khmer language bearing various reflexes of the proposed proto-Mon–Khmer language. By comparing both modern Khmer and Angkorian Khmer numbers to those of other Eastern Mon–Khmer (or Khmero-Vietic) languages such as Pearic, Proto-Viet–Muong, Katuic, and Bahnaric; it is possible to establish the following reconstructions for Proto-Khmer. Numbers from 5 to 10
