70 HISTORICAL ASPECTS
leaves much room for ambiguity, e.g. a llebor for /a lː
j
eβ
~
ǝr/ ‘her/their book’, but a lebor for
/a l
j
eβ
~
ǝr/ ‘his book’ and /a lː
j
eβ
~
ǝr/ ‘her/their book’. In Early Old Irish, nd and mb stand for
/nd/ and /mb/ respectively, but during the Old Irish period they become monophonemic /nː/
and /mː/, a change which renders them freely interchangeable allographs of nn and m(m).
Beginning in Late Old Irish, lenition of f and s is marked by a superposed punctum
delens, ḟ = Ø and ṡ = /h/. Before that, lenition was not indicated orthographically. Occa-
sionally a punctum stands over ṁ and ṅ when they are the product of the nasal mutation.
In that way iṅgen /iŋ
j
g
j
ən/ ‘nail’ could be distinguished from ingen /in
j
ɣ
j
ən/ ‘daughter’.
Vowel signs
The letters a, e, i, o, u represent the vowels /a/, /e/, /i/, /o/, /u/. Vowel length is indicated, if
at all, by the use of the acute accent, i.e. á, é, í, ó, ú. The diphthong /oj/ is written óe or oí,
/aj/ is written áe or aí, /iǝ/ is expressed by ía, /uə/ by úa. This is an idealization; the length-
mark may or may not be written on any element.
The greatest challenge in OIr. orthography is to give graphic expression to palatali-
zation. This is achieved by a complex, but nevertheless defi cient, system in which vowel
signs are employed as diacritics to indicate the quality of the neighbouring consonants.
The main pillars of this system are the support vowels i, which before a consonant usu-
ally indicates its palatalization (e.g. beirid /b
j
er
j
ǝð
j
/ ‘(s)he carries’ or gobainn /goβənː
j
/
‘smiths’), and a, which after a consonant usually indicates its non- palatalization (e.g.
carmai /karmi/ ‘we love’). Closely connected with this is the spelling of schwa /ə/
that depends on the quality of the surrounding consonants. If both consonants are non-
palatalized, a stands for schwa, e.g. molad /moləð/ ‘praise’. If the fi rst one is palatalized,
but the second one not, e is used, e.g. claideb /klað
j
əβ/ ‘sword’; in the reverse case ai or i
is used, e.g. canaid or canid /kanəð
j
/ ‘(s)he sings’. If both consonants are palatalized, i is
used, e.g. claidib /klað
j
əβ
j
/ ‘swords’. When next to a labial, schwa tends towards round-
edness and can be written o or u. The letter e serves as a support vowel before word- fi nal
a and o after palatalized consonants, e.g. doirsea /dor
j
s
j
a/ ‘doors’, toimseo /toβ
~
j
s
j
o/ ‘meas-
ure (gen.)’. Notwithstanding the aporias already inherent in the system, these rules are
rarely consistently applied.
NOMINAL MORPHOLOGY
The nominal class includes nouns, adjectives, and pronouns. Pronouns, special in many
respects, will be treated separately. Old Irish has a defi nite, but no indefi nite, article. Arti-
cle, nouns and adjectives are infl ected for gender, number and case. The three genders,
masculine (m.), feminine (f.), neuter (n.), are grammatical, not natural. There are three
numbers: singular (sg.), plural (pl.) and dual (du.), but adjectives have no special dual
forms and use the plural instead. The dual is always accompanied by the numeral ‘2’, i.e.
m. da
L
, f. di
L
.
Five cases are formally distinguished: nominative (nom.), vocative (voc.), accusative
(acc.), genitive (gen.), prepositional (prep.). The nominative denotes the subject (agent
in active, patient in passive sentences), the predicate of the subject, and is used for topi-
calization. The vocative is the form of address and is always preceded by the particle a
L
.
The accusative denotes the direct object and has – to a lesser degree – adverbial mean-
ings (direction, temporal extension); to the latter belongs its use after certain prepositions.
The genitive indicates various attributive, adnominal relations, including possession, and
