315. General Rules for the formation of Verbal Noun.
(a) As a general rule verbs of the first conjugation form their verbal noun in aḋ, if the final consonant of the stem be broad; in eaḋ, if it be slender, as—
| dún, shut | dúnaḋ |
| mill, destroy | milleaḋ |
| mol, praise | molaḋ |
| léiġ, read | léiġeaḋ. |
(b) When the last vowel of the stem is i preceded by a broad vowel, the i is usually dropped in the formation of the verbal noun, as—
| buail, strike | bualaḋ |
| dóiġ, burn | dóġaḋ |
| goin, wound | gonaḋ |
| brúiġ, bruise | brúġaḋ |
The i is not dropped in—
| caoin, lament | caoineaḋ |
| sgaoil, loose | sgaoileaḋ |
| smuain, reflect | smuaineaḋ |
(c) Verbs of the second conjugation ending in in, il or ir generally form their verbal noun by adding t, as—
| díbir, banish | díbirt |
| cosain, defend | cosaint (cosnaṁ) |
| laḃair, speak | laḃairt |
| coigil, spare | coigilt |
