Consonants There are 31 cited consonant
phonemes in Iu Mien. A distinguishing feature of Iu Mien consonants is the presence of voiceless nasals and laterals. • The standard spelling system for Iu Mien does not represent the stop sounds in a way that corresponds to the IPA symbols, but instead uses e.g. , , and to represent . This may stem from an attempt to model the Iu Mien spelling system on
Pinyin (used to represent
Mandarin Chinese), where and represent . The Pinyin influence is also seen in the use of , , and to represent the alveolar affricates and , , and for the postalveolar affricates . The use of to represent the velar nasal means that it cannot also be used to represent , as would be predicted; instead, is used. • According to Aumann and Pan, in a certain Chinese dialect, the
postalveolar affricates are instead
palatal stops (). • According to Daniel Bruhn, the voiceless nasals are actually sequences (i.e. a short nasalized followed by a voiced nasal), while the voiceless lateral is actually a
voiceless lateral fricative . • Bruhn also observed that younger-generation Iu Mien Americans were more likely to substitute the voiceless
nasals and voiceless
laterals with and the
alveolo-palatal affricates with their corresponding
palato-alveolar variants.
Coda Unlike
Hmong, which generally prohibits
coda consonants, Iu Mien has seven single consonant phonemes that can take the coda position. These consonants are . Some of the stops can only occur as final consonants when accompanied by certain
tones; for example, only occurs with the tone or .
Vowels Iu Mien vowels are represented in the Iu Mien United Script using combinations of the six letters, , , , , , and . According to Bruhn, the
monophthongs are , , , , , , , , , and . The
diphthongs are , , , , , , , . Furthermore, additional diphthongs and
triphthongs can be formed from the aforementioned vowels through - or -on-gliding (having or before the vowel). Such vowels attested by Bruhn include , , , , , , , , , , , , , , , , , , , , and . The dialect studied by Bruhn, and described in the above table, has a phoneme that does not have its own spelling, but is represented in various contexts either as or (which are also used for and , respectively). In all cases where is spelled , and nearly all cases where it is spelled , it does not contrast with or , respectively, and can be viewed as an allophone of these sounds. The only potential exception appears to be when occurring as a syllable final by itself, where it has an extremely restricted distribution, occurring only after the
(alveolo-)palatal consonants . The sound may be a secondary development from in this context, although Bruhn does not discuss this issue.
Tones Iu Mien is a
tonal language with six observed
tonemes. In the Iu Mien United Script (the language's most common writing system), tones are not marked with diacritics; rather, a word's tone is indicated by a special marker letter at the end of the word. If a word lacks a marker, then it is to be pronounced with a middle tone. == Grammar ==
