639 Appendix 2: the Gaelic noun
shows possession and is also used after some, mostly compound, prepositions. The dative
case is used with most simple prepositions. In order to avoid confusion, though every noun
in the dative case in the tables has been shown with a typical preposition, care has been
taken to choose examples where no lenition occurs.
2.1.2 The vocative case
Gaelic nouns have another case which has not been shown here. This is the vocative case
which is used when someone is being addressed. Since it is mainly used with people and,
to a lesser extent, animals, it has been omitted in order to simplify the tables. Basically, in
the singular masculine noun, the vocative case takes the same form as the genitive case
lenited* and is preceded by the particle a e.g. a bhalaich! boy! a Sheumais! James!
a chait! cat! The vocative case of feminine singular nouns has the same form as the sin-
gular nominative form, lenited* and preceded by the particle a e.g. a chailleach! old
woman! a chaileag! girl! Adjectives take the appropriate form e.g. a bhalaich bhig! little
boy! a chailleach ghòrach! foolish old woman!
In the plural, all nouns which have their genitive plural the same as the nominative sin-
gular (but lenited*) have the same form with a final a affixed e.g. a bhalacha! boys! a
chata! cats! Before a vowel or a silent combination of letters the introductory a is dropped
e.g. fheara! men! Nouns which have their genitive plural in the same form as the nomi-
native plural (but lenited*) have the vocative case in the same form e.g. a chaileagan! girls!
Again, the adjective takes the appropriate form e.g. a bhalacha beaga! little boys! a chata
matha! good cats! a chaileagan glice! wise girls!
It should be noted here that the exclamation mark is for demonstration purposes only,
and is not obligatory. Its use would depend on the tone employed e.g. A Sheumais, an
cuala tu sin? James, did you hear that? For more information on the use of the vocative
case with Proper Nouns, see Appendix 12 Proper Nouns Section 1.0.
* according to the rules with regard to lenition – see Appendix 8 Lenition.
Let us now examine each type separately. It should be noted that only the indefinite noun
is shown here. The definite article and its effect on the noun is dealt with later.
2.2 Type 1 masculine
balach m. boy
Singular Plural
nom balach a boy balaich boys
gen balaich of a boy bhalach of boys
dat (le) balach (by) a boy (le) balaich (by) boys
Nouns of this type are masculine. This is a very common type, with the majority of mas-
culine nouns belonging to it.
The distinctive feature of this type of noun is that the genitive case is formed by the intro-
duction of the letter i into the last vowel (a process known as ‘slenderisation’). It should also
be noted that the nominative plural is the same as the genitive singular, and that the genitive
plural is the same as the nominative singular lenited. The dative singular and dative plural
cases are identical to the nominative singular and nominative plural cases respectively.
2.2.1 Some nouns in Type 1, however, suffer a vowel change when i is introduced
The accompanying table Table of Vowel Changes in Type 1 Nouns (Fig. 1) shows all the
possible vowel changes with representative examples.
For example, if we refer to the table we can see that the combination of the letters a ⫹ i
most commonly undergoes no change, as shown by the example cat which becomes cait
in the genitive, but may occasionally suffer a vowel change like that in which crann
changes to cruinn or in which falt changes to fuilt. In one case, as shown in the ‘odd
nouns’ at the bottom of the table, a⫹ i gives i as in mac which changes to mic.
