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.

Verbs

Old Tíogall inherits many TAMs directly from Thensarian. In addition, Old Tíogall displays extensive verb allomorphy. There are broadly four verb groups:

• Unprefixed, non-ablauting verbs: e.g. túsaiṁ /ˈtuːsai̯mʰ/ 'he prays', ní·túsa /niːˈtuːsa/ 'he does not pray'
• Unprefixed, ablauting verbs: e.g. sondaiṁ /sondai̯mʰ/ 'he leaves (transitive)', ní·sonda /niːˈsonda/ 'he does not leave (transitive)'
• Prefixed, non-ablauting verbs: e.g. as·tóċa /asˈtoːkʰa/ 'he proves', ní·assaċ /niːˈasːakʰ/ 'he does not prove'
• Prefixed ablauting verbs: e.g. de·scoḃa /deˈskobʰa/ 'he tolerates', ní·tép /niːˈteːp/ 'he does not tolerate'

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