In O. and Mid. Irish t(t), when initial or preceded by s,
always represents voiceless t. In other positions it may
also represent voiced d. In O. Ir. this value of t is regular
after vowels (cét, mod. céad), optional after consonants.
Thurn. Hdb. § 29
Lenition of t is regularly marked in MSS. of all periods.
The pronunciation of th as h dates (
Thurn. Hdb. § 119
from the 11th century, but according to O'Rahilly,
Hermathena xliv 163 ff.
, from the end of the 13th. Previous
to this we must suppose a dental spirant of the type of Germanic þ. th also occasionally alternates with f (pron. h) :
ZCP vi 24 z
cona fuigsin (thuigsin),

, and Mod. Ir. tathaint (—f—). In the
possessive 2 s. (see it) it is sometimes replaced by h— :
ZCP vi 81.19
t resists or loses lenition :
geminated (see infra).

common with d, after final n of a preceding word.
(d) Frequently before initial s- of a closely-following word :
Note also fáitsine `prophecy,'
, in Ml fáissine
fáithsine, q.v. See also
IGT Introd. § 33
a geminated sound results from contact of th and th or dh :
-mitter <*mid-ther, indnite <*ind-nith-the. See
Thurn. Hdb. § 134
ZCP xiii 191.
Nasalisation of t is seldom marked in Old and Middle
Irish, but note occasional spellings like
, and the stereotyped oldaas (taas).
The spelling tt is found occasionally in O. Ir., more frequently in Mid. Ir. In Mod. Ir. nasalisation is marked by a
prefixed d-. Cf. and trí naraid

t frequently results from original d in contact with lenited

<*indṡamail, int ṡúil, int ṡaeguil. This has given rise to the
prefixing of t (where etymologically unjustifiable) as a
sign of lenition :

. Also after voiceless sounds :
(—de), though in such cases etymological
considerations often cause the original d to be restored :
Thurn. Hdb. § 121
. There are
also some cases of th for d due, apparently, to variations in
pronunciation, e.g. búaith (—d),
(do-dona), more usually dídnad. t also represents the
voiced d arising from *nt, *mt in words like cotlud <contuil, cét <*kṃtom etc., and the voiceless t from k+d in
etlae <*ek(s)dāl-, etc.
In loanwords t represents W. t, th, dd (exx.
