A Grammar of Fo

Introduction

Scope and Purpose

This grammar provides a systematic description of the Fo language (the 1943rd 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 Fo.

Typological Profile

It has a small but genuine set of click consonants.

Phonology

Phoneme Inventory

Consonants

Fo has 23 consonant phonemes, a size that falls within a broadly average range.

It has a complete absence of palatal consonants, something which is a rare occurrence indeed, as well as a modest (but clearly contrastive) set of labialised consonants and a small but genuine set of click consonants.

The table below presents the full inventory of consonant phonemes in Fo. The chart lists all places and manners of articulation attested in the language.

Vowels

Fo has 10 vowel qualities, forming a relatively large inventory. The system distinguishes several vowel categories, as indicated in the chart, offering a wide range of vocalic contrasts.

It has phonologically distinctive back unrounded vowels and a fully three-way front–central–back distinction.

Stress and Tones

Fo has neither phonemic stress nor lexical tone. Prosodic prominence and pitch variation are determined by pragmatic and discourse factors rather than by lexical contrasts.

Phonological Processes

Vowel Harmony

The language employs vowel harmony. To be specific, the following vowels change to match the first vowel of the root: /i/ becomes /ɯ/, /e/ becomes /ɤ/, /æ/ becomes /ɑ/.

Writing System

Introduction

Fo is normally written using the Latin alphabet, whose familiarity makes it straightforward for most readers. For clarity and precision, phonetic transcriptions in the International Phonetic Alphabet (IPA) are also provided throughout this grammar.

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

There is one type of clitic in the nominal phrase, namely a proclitic (placed initially), expressing case. a clitic expressing case, comprising mon /mon/ ‘ACT’, dɒb /dɒb/ ‘DAT’, bing /biŋ/ ‘INS’, quegw /kʷeɡʷ/ ‘VOC’, shir /ʃiɾ/ ‘ALL’, shyk /ʃɨk/ ‘LOC’, dɒd /dɒd/ ‘ABL’ and mem /mem/ ‘PART’.

The morphology of the elements of the nominal phrase, i.e., nouns, adjectives, numerals and pronouns, is described below, as is the way that possession is expressed in Fo.

The Noun

The noun in Fo stands alone without any prefixes or suffixes attached to it.

The noun displays the following derivational morphology: 11 suffixes, namely -dy /-dɨ/ ‘little’, -ro /-ɾo/ ‘big’, -ni /-ni/ ‘old’, -quo /-kʷo/ ‘new’, -quy /-kʷɨ/ ‘good’, -sɒ /-sɒ/ ‘bad’, -ngwɒ /-ŋʷɒ/ ‘have’, -gquɒ /-kʼʷɒ/ ‘use’, -ky /-kɨ/ ‘see’, -fy /-fɨ/ ‘make’ and -by /-bɨ/ ‘break’

The Adjective

In Fo, the adjective has the following structure: the root followed by an optional suffix expressing gender, comprising -aaɒsh /-ɑːɒʃ/ ‘masc’ and -yug /-ɨuɡ/ ‘fem’.

Numerals

The numeral in Fo stands alone without any prefixes or suffixes attached to it.

Determiners

In Fo, the determiner has the following structure: the root followed by an obligatory suffix expressing gender, comprising -ơgk /-ɤkʼ/ ‘masc’, -ưt /-ɯt/ ‘fem’ and -eeb /-eːb/ ‘neut’.

Pronouns

The pronoun in Fo stands alone without any prefixes or suffixes attached to it.

In Fo, subject pronouns (but not object pronouns ones) are dropped unless they are stressed. Here is an example where neither of the pronouns are stressed:

Fưm gqueeb.

[fɯm kʼʷeːb]

k-
POS fɯm
love kʼʷeːb
3.fem

“He (the boy) loves her (the girl).”

 (2)

But here, the word corresponding to he (i.e., the subject) is stressed:

Mon wơt fưm gqueeb.

[mon ʋɤt fɯm kʼʷeːb]

mon
ACT ʋɤt
3.masc k-

Compounding

Verbs

Inflectional Categories

All verbal phrase clitics in Fo are enclitics (placed finally), and there are three types: first, a clitic expressing ta, comprising ngungw /ŋuŋʷ/ ‘PAST’; second, a clitic expressing voice, comprising kok /kok/ ‘passive’; and finally, third, a clitic expressing question, comprising tɒch /tɒt͡ʃ/ ‘Q’.

In addition, the verb is structured like this: first, an obligatory prefix expressing negation, comprising gqu- /kʼʷ-/ ‘NEG’ and k- /k-/ ‘POS’; second, the root; and finally, third, an optional suffix expressing mode, comprising -aygw /-ɑɨɡʷ/ ‘imperative’, -ɒɒs /-ɒɒs/ ‘conditional’ and -eäch /-eæt͡ʃ/ ‘optative’.

The verb displays the following derivational morphology: five suffixes, namely -fu /-fu/ ‘begin’, -bi /-bi/ ‘stop’, -bä /-bæ/ ‘continue’, -me /-me/ ‘try’ and -gki /-kʼi/ ‘start’

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.

Fo employs Subject–Verb–Object (SVO) as its basic word order. The subject is followed by the verb, with the object occurring in post-verbal position. This ordering is widely attested across the world’s languages.

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

Mon tygkưưk kơch ngungw nưwưgk.

[mon tɨkʼɯːk kɤt͡ʃ ŋuŋʷ nɯʋɯkʼ]

mon
ACT tɨkʼɯːk
jaguar k-
POS ʃɤt͡ʃ

PAST niʋɯkʼ
hunter

“The jaguar killed the hunter.”

 (17)
Mon histä kor ngungw nưwưgk soong chägw.

[mon histæ koɾ ŋuŋʷ nɯʋɯkʼ soːŋ t͡ʃæɡʷ]

mon
ACT histæ
lion k-
POS t͡ʃoɾ
eat ŋuŋʷ
PAST niʋɯkʼ
hunter soːŋ
daughter t͡ʃæɡʷ
dog

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

 (18)

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 Fo 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, Fo 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.

dơng wuum nash kưtaab

[dɤŋ ʋuːm nɑʃ kɯtɑːb]

dɤŋ
2 ʋuːm
son nɑʃ
friend kitɑːb
book

“your son’s friend’s book”

 (19)

Case Marking

Fo uses active case marking. Intransitive subjects are divided according to how they participate in the event. More agent-like subjects, such as the subject of ‘run’ or ‘shout’, pattern with transitive subjects and take the active or agentive case. Less agent-like subjects, such as the subject of ‘sleep’ or ‘be ill’, pattern with transitive objects and take the patientive or absolutive case. This system makes sense where the grammar treats control, volition or affectedness as more important than the simple distinction between subject and object.

 (24)

Modifiers and Determiners

The ordering of demonstratives, articles (if present), and other modifiers in Fo 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

Fo forms relative clauses by using a head-internal strategy. The head noun appears inside the clause itself, occupying its regular syntactic position. The entire clause functions as a modifier, and its external syntactic behaviour is identical to that of a noun-modifying phrase.

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

Kiräw ngungw nang.

[kiɾæʋ ŋuŋʷ nɑŋ]

k-
POS ŋʷiɾæʋ
pat ŋuŋʷ
PAST nɑŋ
cat

“I patted the cat.”

 (25)

We can now add a relative clause modifying the noun:

Kiräw ngungw nang kơn ngungw ninyk.

[kiɾæʋ ŋuŋʷ nɑŋ kɤn ŋuŋʷ ninɨk]

k-
POS ŋʷiɾæʋ
pat ŋuŋʷ
PAST nɑŋ
cat k-
POS ŋɤn
catch ŋuŋʷ
PAST ninɨk
mouse

“I patted the cat that caught the mouse.”

 (26)

Relative clauses may themselves contain other relative clauses:

Kiräw ngungw nang kơn ngungw ninyk kor ngungw gkugwyw.

[kiɾæʋ ŋuŋʷ nɑŋ kɤn ŋuŋʷ ninɨk koɾ ŋuŋʷ kʼuɡʷɨʋ]

k-
POS ŋʷiɾæʋ
pat ŋuŋʷ
PAST nɑŋ
cat k-
POS ŋɤn
catch ŋuŋʷ
PAST ninɨk
mouse k-
POS t͡ʃoɾ
eat ŋuŋʷ
PAST kʼuɡʷɨʋ
cheese

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

 (27)

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

Kiräw ngungw nang kơn ngungw ninyk kor ngungw gwegw kɒɒqu ngungw gkugwyw.

[kiɾæʋ ŋuŋʷ nɑŋ kɤn ŋuŋʷ ninɨk koɾ ŋuŋʷ ɡʷeɡʷ kɒːkʷ ŋuŋʷ kʼuɡʷɨʋ]

k-
POS ŋʷiɾæʋ
pat ŋuŋʷ
PAST nɑŋ
cat k-
POS ŋɤn
catch ŋuŋʷ
PAST ninɨk
mouse k-
POS t͡ʃoɾ
eat ŋuŋʷ
PAST ɡʷeɡʷ
1excl k-
POS ʋɒːkʷ
buy ŋuŋʷ
PAST kʼuɡʷɨʋ
cheese

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

 (28)

Complementation Strategies

Fo 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:

Mon sɒqu keg ngungw dɒb tood gơnưgw kynɒɒqu ngungw dɒb käsiim.

[mon sɒkʷ keɡ ŋuŋʷ dɒb toːd ɡɤnɯɡʷ kɨnɒːkʷ ŋuŋʷ dɒb kæsiːm]

mon
ACT sɒkʷ
boy k-
POS t͡ʃeɡ

PAST dɒb
DAT toːd
girl ɡenɯɡʷ
apple k-
POS ᵏǀɨnɒːkʷ
surprise ŋuŋʷ
PAST dɒb
DAT kæsiːm
teacher

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

 (29)

Quotes

Fo 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:

Mon sɒqu bar ngungw dɒb tood gwegw fưm dơng.

[mon sɒkʷ bɑɾ ŋuŋʷ dɒb toːd ɡʷeɡʷ fɯm dɤŋ]

mon
ACT sɒkʷ
boy k-
POS bɑɾ
tell ŋuŋʷ
PAST dɒb
DAT toːd
girl ɡʷeɡʷ
1excl k-
POS fɯm
love dɤŋ
2

“The boy told the girl that he loved her.”
