The Future Affirm. adds idh to the Root; in the Negat. it is like the Root; and in the Subjunct. it adds as. A poetic Future Tense terminating in ann or onn, is frequent in the Gaelic Psalms; as, gairionn will call, seasfann will stand, do bheirionn, will give, &c. The Future has no distinction of Number or Person. The Termination of the Future Affirm. and Negat. in many Verbs was formerly fidh, like the Irish; of which many examples occur in the earlier editions of the Gaelic Psalms. In later Gaelic publications, the f has been uniformly set aside[[51]]. The Termination of the first pers. and third pers. plur. is often incorporated with the corresponding Pronoun; as, seinnam cliu I will sing praise, Psal. lxi. 8., Ni fuigham bàs, ach mairfam beo, I shall not die, but shall remain alive, Ps. cxviii. 17., Ithfid, geillfid, innsid, they will eat, they will submit, they will tell, Ps. xxii, 26, 29, 31. [[52]].
In the Imperative Mood, the second pers. sing. is the Root of the Verb. The other persons are distinguished by these Terminations; 1st pers. sing. am, 3d pers. sing. adh, 1st pers. plur. amaid, 2d pers. plur. ibh, 3d pers. plur. adh.
The Terminations peculiar to the 1st pers. sing. and plur. of the Pret. Subj. and of the Imperat. supply the place of the Personal Pronouns; as does also the Termination of the 2d pers. plur. of the Imperative.
The Infinitive is variously formed.
General Rule. The Infinitive is formed by adding adh to the Root; as, aom bow, incline, Infin. aomadh; ith eat, Infin. itheadh.
1. Some Verbs suffer a syncope in the penult syllable, and are commonly used in their contracted form; as,
| Imper. | Infin. |
| Caomhain, spare, | Caomhnadh. |
| Coisin, win, | Coisneadh, Cosnadh. |
| Diobair, deprive, | Diobradh. |
| Fògair, remove, | Fògradh. |
| Foghain, suffice, | Foghnadh. |
| Fosgail, open, | Fosgladh. |
| Innis, tell, | Innseadh. |
| Iobair, sacrifice, | Iobradh. |
| Mosgail, awake, | Mosgladh. |
| Seachain, avoid, | Seachnadh. |
| Tionsgain, begin, | Tionsgnadh. |
| Togair, desire, | Togradh. |
Observe that Verbs which thus suffer a syncope in forming
the Infinitive, suffer a like syncope in the Preterite Subjunctive, and in the Imperative Mood; as, innis tell, Infin. innseadh, Pret. Subj. innsinn, innseadh, innseamaid, Imperat. innseam, innseamaid, innsibh.
