A Grammar of Ruk

Introduction

Scope and Purpose

This grammar provides a systematic description of the Ruk language (the 1773rd one produced by the Language Creator), outlining its sound system, word formation and syntactic structure, with the aim of presenting a coherent account of the language as an integrated whole. Attention has been paid to both regular patterns and minor irregularities, as these together define the internal balance of the language.

The grammar is accompanied by a bilingual dictionary and a collection of illustrative texts, offering material for further study and comparison. The examples have been selected to demonstrate typical constructions and to give a sense of the language in extended use. The description is intended as a reference work for linguists and language enthusiasts alike, and as a foundation for any future research, teaching or creative adaptation of Ruk.

In the following, we shall look at the various components in more details.

There are no clitics in the nominal phrase.

The Noun

The noun in Ruk consists of first, the root; second, an obligatory suffix expressing number, comprising -əf ‘sing’ and -ət ‘plur’; and finally, third, an obligatory suffix expressing case, comprising -əɾ ‘NOM’, -əs ‘ACC’, -ət͡ʃ ‘GEN’, -ət ‘DAT’, -ən ‘INS’, -əw ‘VOC’, -əh ‘ALL’, -əx ‘LOC’, -əj ‘ABL’ and -ək ‘PART’.

The noun displays the following derivational morphology: two suffixes, namely -əjəw ‘little’ and -əɲəm ‘big’

The Adjective

In Ruk, the adjective has the following structure: the root followed by an obligatory suffix expressing number, comprising -əd ‘sing’ and -əf ‘plur’.

Syntax

Basic Clause Structure

Constituent Order

Constituent order describes the typical arrangement of the subject (S), verb (V) and object (O) in simple declarative clauses. It is a fundamental parameter in grammatical description and forms one of the clearest ways of characterising the overall structure of a language’s clause system.

Ruk has basic Subject–Object–Verb (SOV) word order. The subject precedes the object, and the verb appears at the end of the clause. This is one of the most frequent patterns cross-linguistically.

The following examples illustrate the basic, unmarked, constituent order in Ruk.

[ˈdif səˈxiʃəfəɾ ˈdif nəˈɾauɾəfəs ˈbeːɾəbəməm]

ˈdif
the
səˈxiʃ
jaguar
-əf

“The jaguar killed the hunter.”

ˈdif

ˈdif

ˈdif
the
ˈdiːw
dog
-əf
sing
-əs
ACC
ˈnus
eat
-əb
PAST
-əm
indicative
-əm
active

“The lion ate the hunter’s daughter’s dog.”

(16)

The language has a fixed constituent order, and major phrases normally appear in a predictable position in the clause. Movement for discourse reasons is highly restricted: topics and foci are expressed not by rearranging elements, but through dedicated constructions such as clefts, focus clauses or topic–comment frames. Constituents remain continuous, and both the relative order of phrases and the internal structure of each phrase are stable. As a result, significant deviations from the basic word order are ungrammatical, and discourse structure is managed through these specialised constructions rather than through word-order variation.

Noun Phrases

Structure and Order

The internal structure of noun phrases in Ruk reveals typologically significant preferences in the ordering of nominal constituents. This includes the position of adjectives, numerals, and possessors relative to the noun, each of which can offer clues to the overall headedness of the language.

Possessive constructions are head-final: the possessor precedes the possessed noun. For example, Ruk expresses “the child’s toy” with the equivalent of “child toy”. This ordering is found in many SOV and postpositional languages and aligns with a broader tendency towards modifier-first structures.

[ˈt͡ʃun ˈdif ˈfuːməfət͡ʃ ˈdif ˈtauʃəfət͡ʃ ˈdif ˈhifəfəɾ]

ˈt͡ʃu
2.sing
-n

ˈtauʃ
friend
-əf
sing
-ət͡ʃ
GEN
ˈdif
the
ˈhif
book
-əf
sing
-əɾ
NOM

“your son’s friend’s book”

(17)

Case Marking

Ruk uses nominative–accusative case marking. The subject of an intransitive verb and the subject of a transitive verb are treated alike and take the nominative case, while the object of a transitive verb is marked with the accusative case. This is the familiar pattern from many European languages: the grammar groups together the participants that function as subjects and marks the participant affected by a transitive action separately.

Modifiers and Determiners

The ordering of demonstratives, articles (if present), and other modifiers in Ruk provides further insight into the structure of the noun phrase. These elements frequently exhibit fixed positions and may reveal whether the language favours head-initial or head-final patterns.

Complex Sentences

Relative Clauses

Ruk forms relative clauses by placing them before the noun they modify. The modifier takes the form of a finite clause that precedes the head noun without any relative pronoun. The clause shows ordinary clausal structure, with the role of the head noun recoverable from the syntactic position inside the clause.

To illustrate how relative clauses work, let us begin with a simple sentence:

[ˈdif ˈɲobəfəs ɾəˈɲuxəbəməm]

ˈdif
the
ˈɲob
cat
-əf
sing
-əs
ACC
ɾəˈɲux
pat
-əb
PAST
-əm
indicative
-əm
active

“I patted the cat.”

(23)

We can now add a relative clause modifying the noun:

[ˈdif səˈɡiʃəfəs ˈjeməbəməm ˈdif ˈɲobəfəs ɾəˈɲuxəbəməm]

ˈdif
the
səˈɡiʃ
mouse
-əf
sing
-əs
ACC
ˈjem
catch
-əb
PAST
-əm
indicative
-əm
active
ˈdif
the
ˈɲob
cat
-əf
sing
-əs
ACC
ɾəˈɲux
pat
-əb
PAST
-əm
indicative
-əm
active

“I patted the cat that caught the mouse.”

(24)

Relative clauses may themselves contain other relative clauses:

[ˈdif həˈstaɾəfəs ˈnusəbəməm ˈdif səˈɡiʃəfəs ˈjeməbəməm ˈdif ˈɲobəfəs ɾəˈɲuxəbəməm]

ˈdif

-əs
ACC
ɾəˈɲux

-əb

-əm

-əm

“I patted the cat that caught the mouse that ate the cheese.”

(25)

Finally, here is an example containing several layers of embedding:

[ˈmon ˈbijəbəməm ˈdif həˈstaɾəfəs ˈnusəbəməm ˈdif səˈɡiʃəfəs ˈjeməbəməm ˈdif ˈɲobəfəs ɾəˈɲuxəbəməm]

“I patted the cat that caught the mouse that ate the cheese that I bought.”

(26)

Complementation Strategies

Ruk forms complement clauses by nominalising the embedded verb. The nominalised form lacks finite verbal categories and behaves as a noun phrase. Subjects of nominalised clauses occur in the genitive case, and the nominalised verb establishes the semantic content of the complement.

The following example illustrate how complement clauses function:

[ˈdif ˈkosəfəɾ ˈdif ˈxodəfət t͡ʃəˈmasəfəs ˈnaʃəbəməm ˈdif ɲəˈʔeʃəfət t͡ʃəˈnaməbəməm]

-əf

-əb
PAST
-əm

-əm

“It surprised the teacher that the boy had given the girl an apple.”

(27)

Quotes

Ruk expresses quoted or reported speech without a dedicated quotative particle. Quotations appear as ordinary clauses, distinguished only by the surrounding syntactic context or by the use of verbs of speaking.

Here is an example of how quotations are expressed:

[ˈdif ˈkosəfəɾ ˈdif ˈxodəfət ˈmon ˈt͡ʃun ˈt͡ʃobəwəməm ˈsotəbəməm]

ˈdif
