generally argue for this based on distributional evidence (i.e., if clusters, these would be the only clusters in the language, although see below) and dialect evidence (the laterally released dentals in Mong Leeg, e.g. , correspond to the voiced dentals of White Hmong), whereas those in favor of a cluster analysis tend to argue on the basis of general phonetic principles (other examples of labial phonemes with lateral release appear extremely rare or nonexistent). Some linguists prefer to analyze the prenasalized consonants as clusters whose first element is . However, this cluster analysis is not as common as the above one involving . Only used in Hmong RPA and not in Pahawh Hmong, since Hmong RPA uses Latin script and Pahawh Hmong does not. For example, in Hmong RPA, to write , the order Consonant + Vowel + Tone (CVT) must be followed, so it is k + ee + b = , but in Pahawh Hmong, it is just "" (2nd-Stage Version). Syllable structure Hmong syllables have simple structure: all syllables have an onset consonant (except in a few particles); nuclei may consist of a monophthong or diphthong; and the only coda consonants that occur are nasals. In Hmong Daw and Mong Leeg, nasal codas have become nasalized vowels, though they may be accompanied by weakly articulated . Similarly, a short may accompany the low-falling creaky tone. Dananshan has a syllabic (written ) in Chinese loans, such as 'two' and 'child'. Tones Hmong is a tonal language and makes use of seven (Hmong Daw and Mong Leeg) or eight (Dananshan) distinct tones. The Dananshan tones are transcribed as pure tone. However, given how similar several of them are, it is likely that there are also phonational differences as in Hmong Daw and Mong Leeg. Tones 4 and 6, for example, are said to make tenuis plosives breathy voiced (), suggesting they may be breathy/murmured like the Hmong g-tone. Tones 7 and 8 are used in early Chinese loans with entering tone, suggesting they may once have marked checked syllables. Because voiceless consonants apart from tenuis plosives are restricted to appearing before certain tones (1, 3, 5, 7), those are placed first in the table: So much information is conveyed by the tones that it is possible to speak intelligibly using musical tunes only; there is a tradition of young lovers communicating covertly this way by playing on a jaw
