EARLY IRISH 61
language witnessed mainly in the fi fth and sixth centuries, roughly at the same time when
the British languages were similarly affected. The contemporaneous Ogam inscriptions
are valuable in this respect because they directly refl ect some of the transformations that
the language went through prior to the emergence of Old Irish. Occasionally the changes
can be illustrated by one and the same name from different periods. The name that is writ-
ten gen. LUGUDECCAS on an early Ogam stone (CIIC 263) is found as LUGUDUC on
a late one (CIIC 108). The differences are due to apocope, i.e. the loss of the fi nal syllable,
and to vowel reduction in the third syllable. In the corresponding OIr. form Luigdech we
note yet further changes: the middle vowel has undergone syncope, i.e. has been elided,
and the word- internal cluster has become palatalized. What is only partly revealed by the
spelling is that all internal consonants have been subjected to lenition: the original velar
stop C /k/ has become the corresponding fricative ch /x/, likewise the stops G /g/ and D /d/
have been fricativized to /ɣ/ and /ð/, although this is not immediately visible. With these
three forms, almost all major pre-
Old Irish sound changes have been illustrated.
The diachronic developments that led from Proto- Indo- European via Common Celtic
to Old Irish are suffi ciently well understood (the most important of these are conveniently
summarized in McCone 1996). Only fi ne tuning remains to be done in some cases. Im-
portant developments are the extensive, albeit not entire, loss of fi nal syllables (apocope),
loss of medial vowels (syncope) and concomitant consonant changes, lenition and – to a
lesser degree – nasalization, metaphony of vowels before other vowels (raising and low-
ering) and palatalization. The cataclysmic series of phonological changes had the double
effect of transforming the phonemic inventory as a system and of transforming the char-
acter of the language as a whole. These two sides of one coin are best treated separately.
The sound system
The two processes – lenition and palatalization – multiplied the number of consonantal
phonemes. While Primitive Irish had thirteen (or fourteen) such phonemes, Old Irish has
forty-fi ve.
Lenition (‘softening’, from Lat. lenis ‘soft’) as a historical process means the reduc-
tion in the energy employed in the articulation of obstruent sounds and in consequence their
fricativization: t, k, b, d, g > θ, x, β, ð, ɣ. The opposition unlenited vs. lenited was at fi rst
allophonic, but became phonemic with the losses of fi
nal and medial syllables (apocope
and syncope). This affected all Primitive Irish single stops between vowels and most stops
between vowels and l, n, r, whether in medial, initial or fi nal position. The continuants s
and m became h and β
~
respectively. Although not originally part of this package, p, w, l, r, n
were also integrated into the resultant binary opposition unlenited vs. lenited. The marginal
lenition of the loan phoneme p (> ɸ?) > f was introduced in analogy to the other voiceless
stops. For the liquids and n, a dif
ferent strategy was chosen. The inherited articulation was
reinterpreted as the lenited member of the oppositional pair; in unlenited positions, the liq-
uids and n were strengthened and merged with their inherited geminated counterparts. The
precise phonetic effect of this strengthening cannot be recovered, but it is likely to have
involved length, tenseness or fortis gemination. Thus n, r, l gave rise to nː, rː, lː. Finally, w
behaved in yet an entirely different way. In unlenited initial position it became f by sandhi-
phenomena. In some unlenited internal positions it merged with β, but otherwise, especially
when lenited, it was ultimately lost. For that reason, the lenited member of the oppositional
pair involving f is zero, Ø. The only consonant standing outside the opposition unlenited vs.
lenited is ŋ, which can only appear in unlenited contexts. The effects can be gauged by the
changes undergone by a number of early Latin loan words, as shown in Table 4.4.
