Silvinian (autoglossonym: Nyilvö, Silvinian: [ɲil.ʋə]) is a personal conlang. Therefore, this language was made to express her creator's ideas and thoughts as truthfully and accurately as possible, as well as encompassing as few negative ideas as possible, most of them lacking a separate word, instead mostly relying on particles to express those meanings. Furthermore, this language has no intention of being fully naturalistic, even though some naturalist thinking has been done during the conception of this language.

Grammatically and morphologically speaking, Silvinian is an agglutinative, mostly suffixing OVS language, which makes use of postpositions, and lacks "true" adjectives, a function that is fulfilled by nouns. Verbs in this language have a very strict valency distinction, especially for ambitransitives, that may have two or more forms depending on their valency in-context.

Phonology

Silvinian distinguishes between 16 to 25 consonants, depending on whether allophones are counted or not, though the standard is to consider that there are 18 consonants. Similarly for vowels, Silvinian can be analysed as having between 6 and 8 vowels, where the maximum range (8 vowels) is considered to be the standard analysis.

Consonants

	Labial	Coronal	Dorsal	Glottal
Dental	Alveolar	Palatal[1]	Velar
Nasal	m	n̪~n		(ɲ)	ŋ
Plosive	p	t̪~t, d̪~d		(c, ɟ)	k	ʔ
Fricative	ɸ	(θ, ð)[2]	s, z	(ʃ, ʒ)	x	h
Approximant	ʋ~w	l̪~l		(ʎ), j
Rhotic		r̪~r

1. ^a  Palatal consonants (except /j/) are only allophones of coronals (except for [θ] and [ð]) followed by /j/.

2. ^a  [θ] and [ð] are allophones of intervocalic /t/ and /d/.

Further notes

• Syllable-final "n" might be dropped, nasalizing the preceding vowel, as in "hatyön", which is pronounced anywhere between [ha.ˈcɵn] and [ha.ˈcɵ̃].
• Nasal consonants assimilate in place of articulation with the following consonants, and precedes nasalization in rule order, like in "ándyas", pronounced [æːɲ.ɟas], and not *[æ̃ː.ɟas].
  • The cluster [ɲɟ] (or any nasal-plosive cluster) can also be pronounced as a pre-nasalised stop like [^ɲɟ].
• Intervocalic non-geminated plosives lenite into fricatives (see §Consonant lenition for more).

Vowels

	Front	Central	Back
High	i, (ɪ)[1]		u, (ʊ)[1]
Mid	e	(ə)[2], ɵ	o
Low	(æ)[3]	a	(ɒ)[4]

1. ^{a  b}  Short [i] and [u] can be pronounced as [ɪ] and [ʊ]

2. ^a  [ə] is considered as an alternate realization of short [ɵ], but is also used to "break" some consonant clusters.

3. ^a  [æ] is considered as an alternate realization of long [a].

4. ^a  [ɒ] does not exist outside of diphthongs (see §Diphthongs for more).

Vowel length

In Silvinian, every vowel can be long, with length being written with an acute, or with a double acute in the case of "ö".

Furthermore, vowel length is contrastive, meaning that the meaning of a word changes whether a vowel is short or long:

Minimal pairs

Vowel	Short vowel			Long vowel
	Word	IPA	Meaning	Word	IPA	Meaning
[a~æ]	sar	[sar]	(living) fish	sár	[sæːr]
[e]	cyern	[kjern]		cyérn	[kjeːrn]
[ɪ~i]	mit	[mɪt]~[mɪθ][1]		mít	[miːt]~[miːθ][1]
[o]	ryon	[rjon]~[rjõ]		ryón	[rjoːn]~[rjõ]
[ʊ~u]	u	[ʊ]		ú	[uː]
[ə~ɵ]	sönt	[səⁿt]~[sə̃θ][1]		sőnt	[sɵːⁿt]~[sɵ̃ːθ][1]

1. ^a b c d  The second pronunciation for each of those words correspond to the way they are pronounced before vowels.

Diphthongs

In theory, Silvinian has 6 diphthongs, which are:

• /aj/~/aɪ̯/
• /ej/~/eɪ̯/
• /oj/~/oɪ̯/
• /aw/~/aʊ̯/
• /ew/~/eʊ̯/
• /ow/~/oʊ̯/

In non-careful speech, however, some distinctions are loss, and some diphthongs even monophthongize.

Diphthongs in careful and non-careful speech

Careful speech	Non-careful speech
/aj/~/aɪ̯/
/ej/~/eɪ̯/	[eː]
/oj/~/oɪ̯/	[ɒj]~[ɒɪ̯] > [aj]~[aɪ̯]
/aw/~/aʊ̯/
/ew/~/eʊ̯/
/ow/~/oʊ̯/	[oː]

Consonant lenition

Vowel-triggered lenition

In most cases, between vowels, plosives lenite and become fricatives, whether within a word (internal lenition) or across word boundaries (external lenition)

Initial	Lenited
/p/	[ɸ]
/t/	[θ]
/d/	[ð]
/k/	[x]

Internal

Internal lenition can almost never be blocked, unless adding a "dyerá" just after the consonant, written as an apostrophe. The "dyerá", in this case, acts as an ultrashort schwa, which may or may not be pronounced.

Just like vowel length, lenition also creates minimal pairs, such as with "cadá" (pronounced [kaðæː]) and "cad'á" (pronounced [kad(ə̆)æː]), although those are very much rarer.

External

External lenition (a type of external sandhi) happens when a word ends in VP, and the following word starts with V where:

• V is a vowel
• P is a plosive

It can never be blocked, except in very rare cases involving certain particles.

Consonant-triggered lenition

In addition to intervocalic lenition, some consonant-initial words can cause lenition, which, in this case, is very similar to assimilation, and follow the same patterns as intervocalic lenition.

In this case, consonant lenition happens when the word ends in "iP" and the following word starts with "F", where F is a fricative. One very good example of a lenition trigger is the particle "sá", with "fáid sa" being pronounced as [ɸæːjð‿sa]

Phonotactics

Syllable structure

The maximum syllable structure is CSVVC, where:

• C is a consonant (it can be any sound, as long it doesn't break the following rule)
• S is an approximant, nasal or rhotic (the only restriction to this is that 2 consonants with the same manner of articulation can't follow each other, so "svei" is valid, but *"mnis" isn't)
• V is a vowel (the second vowel in a syllable can only be /ɪ/ or /ʊ/ and their long equivalents /iː/ and /uː/)
