Phonology

Phonological inventory

LNS oglang and auxlang use the same set of phonemes for standard speech. The consonant and vowel charts are provided below.

*'w' is a coarticulated consonant.
Manner Place	Bilabial	Alveolar	Palatal	Velar	Glottal
Nasal	m	n
Stop	p	t		k
Fricative		s			h
Approximant			j	(w)
Lateral approximant		l

	Front	Back
Close	i	u
Close-mid	e	o
Open	a

Allophones

There are positional allophones available for LNS oglang, for easier pronunciation. But, it doesn't allow free variants in principle, although inevitably being a secondary language leads to the usage of unofficial variants. The following chart shows how allophones appear when /n/ meets an ensuing consonant.

Positional allophone	Place of articulation	Following consonant
m	Bilabial	m, p
n	Alveolar	n, t, s, l
ɲ	Palatal	j
ŋ	Velar	k, w
ɴ	Glottal	h

LNS auxlang provides the entire IPA chart for free variant allophones, to accomodate the phonological inventories of multiple languages. This large number of allophones are also used to phonologically adapt words that are loaned from other languages to fit the phonemes of LNS.(Loanwords will be discussed in the vocabulary section.)

*Stop-fricative sequences are split into separate syllables.

Phonotactics

The syllable structure in LNS is CV or CVn. CVn appears only at the first syllable of every word, and does not allow a glide at its onset. There's an optional nGV syllable, to distinguish between CVn-GV and CV-nV where the glide might not be heard well. Thus it only appears at the second syllable(after the coda /n/). In auxlang, due to some languages that do not use glides under certain conditions, diphthongs may be allowed(e.g. w→u in German, je→ie in Japanese). Below is an example of a word that includes all possible syllable structures.
