THE LATIN
DATIVE
PLUEAL.
generally
terminates
in
"
aibh." This
termination
is
plainly
related to the old Latin
dative
in
^ubus"
and
"
abus,"
which
was
probably
the
genuine
and
original
form of the case
in
Latin. The Sanscrit
dative
plural
ends
in
"
abhyas,"
or,
at
least,
in
"
bhyas,"
after a
vowel,
as
"rajabhyas,"
Latin
"
regibus,"
Irish
"riogaib,"
to
kings.
In these
respects
there
is
a
remarkable
cognation
between
the Keltic and the Sanscrit."
The
ending
"
bus"
of the
dative
plural
of
Latin
nouns
is found
in the
third declension
only
;
in the
fourth
and
fifth,
too,
but these are mere
developements
of
the
third.
This
omission is
a
falling
away,
and
a
sign
of
weak-
ness
in the
early days
of
Latin
linguistic
developement.
The
termination
"
iB"
(ft,
aspirated,
has the
sound of
"
v"
when
articulated
in
the same
syllable
with
"
i")
or
"
aibh"
is
found
in
Irish not
in
one
declension,
but
in
all. Ex-
