Myrkçam has a moderately small inventory of 17 consonant phonemes, summarized thus:

            Bilabial    Dental      Alveolar    Alveolopal. Palatal     Velar
Nasal       m                       n                       ɲ           ŋ
Plosive     p                       t                       c           k
Fricative   ɸ           θ           s           ɕ           ç           x~h
Approximant                                                 j
Lab. Approx.                                                            w
Trill                               r

The plosive series contains only the four plosives /p t c k/. All plosives remain unaspirated in all positions in the standard central dialect. No dialect maintains any distinctions of aspiration. Plosives can, however, be slightly labialized before rounded vowels: [pʷ tʷ cʷ kʷ].

The nasal plosives correspond to these oral plosives, comprising /m n ɲ ŋ/. Nasal plosives preceding oral plosives, fricatives, or other nasal plosives across syllable boundaries or within the same syllable assimilate to the corresponding place of articulation. Almost always this occurs at syllable boundaries, as, of these combinations, the syllabic structure of Myrkçam would only permit /mn/, /ɲn/, or /ŋn/ to occur tautosyllabically. Additionally, in all positions /ɲr/ becomes [nr], but no other nasal is assimilated by /r/. A phonotactic constraint forbids /tŋ/ from occurring, and so when it would otherwise appear at syllable boundaries it becomes [tk].

The set of fricatives is comparatively large, consisting of /ɸ θ s ɕ ç x/. It is also the set that is subject to the most variation: while the standard central dialect realizes it as [ɸ θ s ɕ ç x~h] when unvoiced, in some dialects its realization can vary to [f θ s ʃ ç x~h]. In particular the nonstandard use of [f~v] for /ɸ/ has become quite widespread in recent times. Regardless of dialect, /x/ is realized as [x] syllable-finally or when in a consonantal cluster but otherwise realized as [h], disregarding voicing.

Myrkçam has one rhotic consonant /r/ and two approximants /j w/. The rhotic /r/ typically averages two or three taps, but in informal speech it may be reduced to [ɾ] when between two vowels. /w/ only occurs before unrounded vowels. In any case, neither /w/ nor /j/ show any significant variation or allophony, and they are primarily found in diphthongs.

If doubled tautosyllabic consonants arise from morphological or other concerns, they are phonologically reduced to single consonants rather than geminated.

The inventory of vocalic phonemes is larger than average, with ten present:

            Front                   Back
            Unrounded   Rounded     Unrounded   Rounded
High        i           y           ɯ           u
Mid         e           ø           ɤ           o
Low                                 a           ɶ

Despite their position in the phoneme table above, /a/ and /ɶ/ are not treated as back vowels but as central ones; in formal speech, they are typically pronounced centralized, as [ä] and [ɶ̈]. This ideally would result in a symmetric vowel system.

The actual realization of the vowel phonemes can show considerable variation by dialect, but as a rule, the rounding distinctions are preserved. In many dialects the rounded front vowels and the unrounded back vowels are centralized to some extent, especially in unstressed positions. This tends to cause both /y/ and /ø/ to approach [ʏ], while /ɯ/ becomes [ɯ̽] and /ɤ/ becomes [ʌ̽]. Many of these dialects also realize /ɶ/ as [ɔ̽], with such vocalization again more common in unstressed positions. 

Centralization of /i/, /e/, /u/, /o/, or /a/ is less common; these phonemes are realized more consistently across dialect, whether stressed or unstressed, as [i], [e̞], [u], [o̞], and [ä], respectively, though they may lose some vowel quality when unstressed.

In addition to the above variations in realization, unstressed vowels are in all dialects shorter than stressed vowels.

Diphthongs exist in /w/ and /j/, but /w/ can only occur before unrounded vowels. All vocalic variations still apply to the vocalic elements of diphthongs.

The value here is 1.7, considerably below the natlang mean of 4.25.

Myrkçam may seem somwhat atypical in that it observes no voicing distinction (a feature shared by about a third of all languages); nonetheless, both voiceless and voiced consonants occur, in complementary distribution. /m/, /n/, /ɲ/, /ŋ/, /j/, /w/, and /r/ are always voiced; all other consonants are voiceless except when they fall between two other voiced phonemes or when they fall immediately after a nasal plosive, in which case they become voiced. This rule is not applied recursively.

Myrkçam makes no voicing distinction.

Vowels are partially nasalized when preceding nasal plosives, but this is not distinctive.

Syllables in Myrkçam maintain the sonority sequencing principle. In particular, the sonority hierarchy for Myrkçam is as follows, from highest to lowest:

/a ɶ/
/e ø ɤ o/
/i y ɯ u/
/j w/
/r/
/n/
/m ɲ ŋ/
/ɸ θ ɕ ç x/
/s/
/t/
/p c k/

Syllables are limited to a (CA)V(A), (CA)V(C), or (C)(C)V(A)(C) structure, where V represents any vowel, C represents any consonant, A represents any of the phonemes /r j w/, and parentheses represent optional elements. The only exception to this occurs when a nasal precedes a fricative across a syllable boundary, in which case an oral plosive at the fricative’s place of articulation is intercalated at the end of the first syllable regardless of structural constraints.

Secondary stress is not iterative, and it occurs at the opposite edge from primary stress, making it always fall on the initial syllable.

Specifically, /θ/ and its allophones are present.

Myrkçam is a highly agglutinative language, hence its monoexponential concatenative morphology.

Myrkçam verbs are conjugated to agree with their subjects in person (exclusive first, inclusive first, second, present but not addressed, proximate, obviate, or hypothetical) and number (singulative, transnumeral, or plural).

Verbs mark three tenses (past, present, and future), three aspects (perfective, imperfective, and inchoative), and seven moods (indicative, imperative, subjunctive, potential, negative, participial, and infinitive). The prefices of a verb are always attached in the order aspect-tense-mood-number-person, resulting in a final construction in the reverse order: person-number-mood-tense-aspect-stem.

Thus, there are five categories per word.

Verbs are conjugated and subjects and objects are declined, each in agreement with the other.

The genitive case is used to indicate that the marked noun is modifying another noun (which typically precedes it).

Coordination is accomplished differently for different syntactic elements. Clauses are coordinated via one of a moderately small set of coordinating conjunctions, which is interposed between the clauses. Some common members of this set include ‹orm› “and”, ‹aš› “and, but”, ‹îš› “but”, ‹za› “but rather”, ‹hwat› “either… or”, ‹izi› “… or… or both”, ‹hjan› “resulting in, then”, ‹hwi› “for the motivating reason that, because”, ‹śa›, “logically implies that”, ‹ńug› “from the cause that, because”, and ‹pfâ› “so that”.

Coordination of noun phrases, of verb phrases, and of heads of phrases in general, by contrast, is accomplished via simple juxtaposition (asyndeton), with no intervening conjunction. To express semantic relations and nuances among the coordinated elements, particles may be added after the elements.

WALS instructs that, if noun phrases and verb phrases are coordinated similarly, but clauses differently (as in Mîrkšam), “Differentiation” should be used as the classification.

Rather than "no dominant order", this is actually VXO, the only order that is unattested in any natlang (and which is therefore not listed by the WALS). This may be the only case in which Myrkçam violates a universal.
