Verbal Affix

In änglosax, all nouns can be declined directly into a stative predicate, "to be X / be X" without a separate verb. This function is carried out by the verbal affix. Which acts as a pseudo-case as it replaces the case the noun had previously.

Morphology

The verbal affix is -yn, it doesn't distinguish plural:

Examples

1. fer (fire) -> feryn (≈ to be fire / be fire)

2. god (good) -> godyn (≈ to be good / be good)

Copula shenanigans

In the present tense, the copula is emmited directly. The verb declined noun alone carries the full predicate meaning:

wu feryn · You are fire

In lexical tenses (excluding the present tense), the tense suffix becomes a particle:

wu é feryn · You were fire

But in copula tenses, the copula returns but the verbal affix is still kept:

wu beu godyn · You will be good
