Meixian dialect

There are two series of stops and affricates in Hakka, both voiceless: tenuis /p t ts k/ and aspirated /pʰ tʰ tsʰ kʰ/.

* When the initials /k/ ⟨g⟩, /kʰ/ ⟨k⟩, /h/ ⟨h⟩, and /ŋ/ ⟨ng⟩ are followed by a palatal medial /j/ ⟨i⟩, they become [c] ⟨g(i)⟩, [cʰ] ⟨k(i)⟩, [ç] ⟨h(i)⟩, and [ɲ] ⟨ng(i)⟩, respectively.[1]

Moiyan Hakka has 7 vowels, ɹ̩, i, e, a, ə, ɔ and u, that are romanised as ii, i, ê, a, e, o and u, respectively.

Moreover, Hakka finals exhibit the final consonants found in Middle Chinese, namely [m, n, ŋ, p, t, k] which are romanised as m, n, ng, b, d, and g respectively in the official Moiyan romanisation.

Moiyan Hakka has 6 tones. The Middle Chinese fully voiced initial syllables became aspirated voiceless initial syllable in Hakka. Before that happened, the four Middle Chinese 'tones', ping, shang, qu, ru, underwent a voicing split in the case of ping and ru, giving the dialect six tones in traditional accounts.

These so-called yin-yang tonal splittings developed mainly as a consequence of the type of initial a Chinese syllable had during the Middle Chinese stage in the development of Chinese, with voiceless initial syllables [p- t- k-] tending to become of the yin type, and the voiced initial syllables [b- d- ɡ-] developing into the yang type. In modern Moiyan Hakka however, part of the Yin Ping tone characters have sonorant initials [m n ŋ l] originally from the Middle Chinese Shang tone syllables and fully voiced Middle Chinese Qu tone characters, so the voiced/voiceless distinction should be taken only as a rule of thumb.

Hakka tone contours differs more as one moves away from Moiyen. For example, the Yin Ping contour is ˧ (33) in Changting (長汀) and ˨˦ (24) in Sixian (四縣), Taiwan.

Entering tone

Hakka preserves all of the entering tones of Middle Chinese and it is split into two registers. Meixian has the following:

• 陰入 [ ˩ ] a low pitched checked tone
• 陽入 [ ˥ ] a high pitched checked tone

Middle Chinese entering tone syllables ending in [k] whose vowel clusters have become front high vowels like [i] and [e] shifts to syllables with [t] finals in modern Hakka[3] as seen in the following table.

For Moiyan Hakka, the yin ping and qu tone characters exhibit sandhi when the following character has a lower pitch. The pitch of the yin ping tone changes from ˦ (44) to ˧˥ (35) when sandhi occurs. Similarly, the qu tone changes from ˥˧ (53) to ˦ (55) under sandhi. These are shown in red in the following table.

The neutral tone occurs in some postfixes. It has a mid pitch.
