Athi
in late MSS, wrongly abstracted from Nathi
(understood as n-Athi) and such phrases as bidathí a ainm,
Cóir Anm. § 146
= bid Dathí, &c.
Already in the 11th century the meaning and origin of
the name had become obscure to the Irish grammarians. It was associated with daith, daithe,
swift, swiftness
(and the npr. Daithe, Daithem, Daithen) as
is clear from the marginal note
LU 38 a
: is de atberthea a
nainm sin fris conid Dathi a ainm óndní is dathi gabálaid
(
ó daithi a gabáltais,
YBL 191 b 20
, where the note has
been adopted in the text), cf.
Cóir Anm. § 146
. The length
of the final -í is attested by the archaic spelling Nathíi and
the rhyme with
trí,
MacCarthy 212. 2
(LL). Dathí as the
later form originated from the confusion of the N- of Nathí
with the eclipsing n- after a preceding accusative or neuter
noun: tech Nathí (understood as t. nDathi),
babtizauit
Echaich mac Nathí (mac nDathi) &c.
MacCarthy 212. 2
(LL): cethri cóic bliadna 's a trí:
rogiallad do niurt Nathí (v.l. Dathi, BB): i Sléib Elpa na
narm nán, &c. I have no example of Dathí alliterating with
d- from old poetry. The accent falls on the ultimate, cf. the
alliteration Na-thí:
tolchar,
LL 150 b 30
,
31 b 45

Gorm. Aug. 1
. With
Nathíi should be compared the npr. f. Daríi, the authoress
of the Cáin Daríi; -íi seems the g
s. of a npr. m. the nom. of
which would be Old-Ir. Eo, identical with the tree-name (cf.
the npr. given by Meyer,
Sitzungsb. Pr. Akad. 1912 xxxviii 798
).
This name actually occurs
TBC-LL¹ 4870
: co hEo mac Oircne.
LL 94 b 7
f.b.
: co hEo mac Forne. The genitive Íi, Í occurs
in the npr. Mac Híí in the Oir. text
Anecd. iii 61. 6
, Mac
Hí (the name of a deacon)
LL 366 e 11
. Compare the ivo- of Ogh. IVOCATTOS (Eochad), IVODACCA (†Eodach, not
Uadag, as Macalister thinks,
Epigr. iii 180
), Gaul. IVORIX
in a memorial inscription from Bordeaux. Nathíi `the
nephew of Eo,' then, would be (†) in Ogh. NETTA IVI (NIOTTA
IVI) of the nephew of Eo, and in the book of Armagh †Nioth
Íi, Niath Íi (cf.
Nioth Fráich,
Ardm.
15 b 2
,
Niath Taloirc,
25 b
).
For dar of Dar-Íi cf. dar and der; the parallelism between
Nath-Fráich and Der-Fráich (niece of Fraech ?) is noteworthy.
