Hrmitt is an accusative VSO language with subject incorporation and agglutinative tendencies.
Two of its most prominent features are the possessive construction with prononimal affixes (section 3.1.1.1), and the derivation of verbs as the instrumental case of noun stems (3.3). Future tense is marked by evidentials (4.5), and past tense is marked by switching to a different set of pronominal affixes, with the irrealis mood indicated by the presence of both (4.9).
The possessive construction doubles as subject incorporation (3.3.3), and verbs largely retain their instrumental noun meaning. Due to difficulties in reconciling the behaviour of Hrmitt verbs with verbs as we know them in human languages, some analysts have proposed that Hrmitt is either verbless, or that it only has two verbs in the form of the -mi and -ni suffixes. Such proposals are not without their own difficulties, however; so for the purposes of this grammar, we will follow the traditional analysis of -mi and -ni as verbalising suffixes that derive verbs from noun stems.
Phonologically, Hrmitt features complex segments with frequent consonant clusters. One of the most distinguishing features of its phonology is the fricativisation of initial consonants in a cluster (2.3.2.2), which gives Hrmitt its characteristic sound.
