Appendix:Irish verbs

Analytic and synthetic forms
Analytic forms have information about tense only, e.g. molann, molfaidh, etc. Pronouns must be used to add personal information, e.g. molann sibh.

Synthetic forms (as the name suggests) "join together" an analytic form and a pronoun, e.g. molann + mé > molaim.

Suffix notes

 * ~ Bare radical form.
 * + Add the analytic suffix to the root.
 * L Initial lenition of radical/root.
 * † Dialect form.
 * The tenses are listed slightly differently than in general on Wiktionary, in order to show the indicative present beside the future, and the indicative past habitual beside the conditional.
 * The shorter of a suffix's broad and slender forms is shown, e.g. &#8209;ann for &#8209;(e)ann; &#8209;fidh for &#8209;f(a)idh.

Independent and dependent forms
Independent and dependent forms derive from the related ideas of absolute and conjunct forms (for simple verbs), and prototonic and deuteronic forms (for complex verbs), in Old Irish. The forms are identical for all regular verbs in Modern Irish, and are clearly seen only in some of the tense forms of some of the irregulars.

Verbal adjectives
The verbal adjective root is slender or broad, derived from the radical. The basic suffix is &#8209;t&#x0259;, which may or may not be lenited/aspirated, and the final &#x0259; is broad (a) or slender (e) in agreement with the adjective's root. Therefore, the possible set of altered suffixes is &#8209;ta, &#8209;tha, &#8209;te, &#8209;the. The formation rules are well defined and are applied regularly with very few exceptions.


 * 2nd conjugation -im, -in, -ir (but not -il): root is broadened
 * 2nd conjugation -is: root is syncopated
 * verbs in -igh: drop the gh, exposing the vowel i
 * dntls, th, vowels: suffix is not lenited
 * for -th, -thte > te,
 * verbs in -bh, -mh: bhth, mhth > f

Examples following these rules
 * foghlaim, foghlamtha
 * oscail, oscailte
 * inis, inste
 * glan, glanta
 * nigh, nite
 * ith, ite
 * scríobh, scríofa

Declension of verbal nouns
The declension of verbal nouns depends on context. When used for example as substantive, they are declined with the appropriate noun declension. The gender of the verbal noun tends to follow that of the declension, but there are exceptions.
 * first declension:, óil
 * second declension:, titime
 * third declension:, foghlama
 * fourth declension:, ithe

When verbal nouns are in infinitive context, they are declined using the verbal adjective.
 * ól, ólta
 * titim, tite
 * foghlaim, foghlamtha
 * ithe, ite

However, certain verbal nouns are always declined using the verbal adjective, irrespective of context.
 * socrú, socraithe, socruithe

Copula
The copula  exists in only three tenses: It is not declined.
 * indicative present (and future)
 * indicative past (and conditional)
 * subjunctive present

Defective verbs
There is only a handful of defective verbs in Irish, notably: The copula  (see above) is also regarded as a defective verb.
