Tigol/Morphology

Morphology is the most complex part of Old Tíogall. Much of Proto-Talmic morphology survives in Old Tíogall. However, Old Tíogall is most notorious for its often unpredictable verbal allomorphy.

Verb TAMs

Old Tíogall inherits many TAMs directly from Thensarian. In addition, Old Tíogall displays extensive verb allomorphy. Verbs can be grouped in two ways: non-prefixed and prefixed, and non-ablauting and ablauting. The verb tables below will use the following example verbs:

• Unprefixed, non-ablauting verbs: e.g. túsaiṁ /ˈtuːsai̯mʰ/ 'he prays', ní·túsa /niːˈtuːsa/ 'he does not pray' (modern tús)
• Unprefixed, ablauting verbs: e.g. sormaiṁ /sormai̯mʰ/ 'he finds (intransitive)', ní·sorma /niːˈsorma/ 'he does not find' (modern sorm)
• Prefixed, non-ablauting verbs: e.g. as·tóċ /asˈtoːkʰ/ 'he proves', ní·assaċ /niːˈasːakʰ/ 'he does not prove' (modern stóch)
• Prefixed ablauting verbs: e.g. dos·coḃ /dosˈkobʰ/ 'he tolerates' (*de-as-coḃ), ní·dep /niːˈdep/ 'he does not tolerate' (modern doscabh)

In case where there is a preverb, the first syllable after the interpunct is stressed.

Conditional

Partially influenced by optative, partially by preterite
