316. There are, however, many exceptions to the above rules. The following classification of the modes of forming the verbal noun will be useful.
(a) Some verbs have their verbal noun like the stem, e.g., fás, grow; ól, drink; riṫ, run; snáṁ, swim, &c.
(b) Some verbs form their verbal noun by dropping i of the stem, e.g., cuir, put or send, cur; coisg, check, cosg; sguir, cease, sgur; guil, weep, gul, &c.
(c) Some verbs add aṁain or eaṁain to the stem to form their verbal noun, e.g., caill, lose, cailleaṁain(t); creid, believe, creideaṁain(t); fan, stay, fanaṁain(t), lean, follow, leanaṁain(t); sgar, separate, sgaraṁain(t), &c.
In the spoken language t is usually added to the classical termination ‑aṁain.
(d) A few add an or ean for the verbal noun, e.g., leag, knock down, leagan; léig, let or permit, léigean; tréig, abandon, tréigean; teilg, throw or cast, teilgean.
