# Background

**Language Family:** Trans-New Guinea, Main Section, Central and Western, Huon-Finisterre, Huon, Eastern

* Dedua is spoken in the Morobe province of Papua New Guinea.

# Phonology

## Consonants

* Based on the comparison with other languages in the same language family, @McEvoy2005 concludes that voiceless stops in syllable codas are neutralized and realized as glottal stops (p. 269). Thus, the phonemic status of the glottal stop is called into question. However, I have opted to treat it as a phoneme here because this seems to be the common practice found in the literature.

```{r echo=FALSE, message=FALSE, warning=FALSE, results = 'asis'}

library(dplyr)
library(knitr)
library(kableExtra)


consonants <- read.table(textConnection('
"Manner of Articulation"   Labial     Alveolar  Alveopalatal    Palatal     Velar    Glottal  
Stops                      "p  b"     "t  d"        ""            ""     "k kp ɡ ɡb"   "ʔ"

'), TRUE)

kable(consonants, col.names = c("Manner of Articulation", "Labial", "Alveolar", "Alveopalatal", "Palatal", "Velar", "Glottal"), align = 'c') %>%
  kable_styling("bordered") %>%
  add_header_above(c("", "Place of Articulation" = 6)) %>%
  column_spec(1, bold = TRUE) %>%
  footnote(general = "Note: For phonemes that share a cell, those on the left are voiceless and those on the right are voiced. /kp/ and /ɡb/ are labiovelar stops.", general_title = "")
```

## Vowels

* According to @McEvoy2005, the diphthongs listed below are always interpreted as complex nuclei (p. 270).

```{r echo=FALSE, message=FALSE, warning=FALSE, results = 'asis'}

vowels <- read.table(textConnection('
         Front      Central       Back
High      "i"         ""          "u"
Mid       "e"         ""          "o"
Low        ""         "a"          ""
'), TRUE)

kable(vowels, align = 'c') %>%
  kable_styling("bordered") %>%
  column_spec(1, bold = TRUE)


diphthongs <- read.table(textConnection('
Diphthongs
"/ei/, /eu/, /ai/, /au/, /oi/, /ou/"
'), TRUE)

kable(diphthongs, align = 'c') %>%
  kable_styling("bordered")
```

# Alphabet

```{r echo=FALSE, message=FALSE, warning=FALSE, results = 'asis'}

alphabet <- read.table(textConnection('

# Syllable Structure

* Syllables in Dedua consist of the following structures [@ceder_dedua_2003, p. 3]:
    - V
    - VV
    - VC
    - CV
    - CVV
    - CVC
    - CVVC
* Glottal stops and /ŋ/ are the only phonemes that appear in syllable codas [@McEvoy2005, p. 268]. This makes for the inference that complex consonants are always realized as such rather than two separate phonemes.

# Lenition Rules

* /ʔ/ becomes [h] syllable-initially [@ceder_dedua_2003, p. 3].

# Misc. Rules

* /r/ varies freely with [l] intervocalically [@ceder_dedua_2003, p. 3].
* /w/ varies freely with [v] (ibid.).
* In syllable coda position, the velar nasal undergoes assimilation to the place of articulation of the following consonant if present. This assimilation is reflected in written Dedua [@McEvoy2005, p. 268]; however, it has been accounted for in the rules to reflect /ŋ/ as underlying.
