Non-voynichese word on f68r2

[ololololo]

This word is not on Voynichese, obviously, was left by the author/scribe himself.

It is in a circle with the Voynichese words. The first letter (which is clearly a Latin s) and the third letter (maybe an n) are what distinguish this word. The word is also highlighted by the fact that there are connections between the letters (marked in dark red in the image below), and the distance between them is quite small.
I tried to draw the letters that I could see here:

At least this word has 4 letters, the final one is not identified for sure. The word looks similar to the Bavarian "Suna" (the sun), which is consistent with the sun that is supposedly drawn nearby. However, it is unclear why u has a tail...
If it's a contraction, we won't be able to decipher it.

What do you think?

I just looked at the image and the two words preceding also didn't look like Voynichese to me. I saw Cuo a sona, I put it into a translator, got told it was Spanish and means 'it rings here'? I do not know. Tried with sond, suna, it won't translate it at all. Suna by itself it told me was English. Tried another translator, no results at all with any of it.

According to the Bavarian dictionary, the sun is Sunn, but on the Internet and using AI (please forgive me, forum, for using it; I don't know Bavarian) I also found the variant Suna. It's not a fact that it's the sun at all. We only have the letters s and n.

The interlinear has some voynichese variations:

<f68r2.L.1;H>      okeo.okoaiin.okol.oky.oeeeo.r.ekey.okcho!l.cheo.o.koiin.
<f68r2.L.1;R>      okey.otoaiin.opol.oky.oshed.r.*key.okeeo!l.chey.o.!***!.
<f68r2.L.1;U>      okey.okoaiin.okol.o**.oeeeo,r.okey.okeeo!l.cheo.o,****!.
<f68r2.L.1;V>     
okey.okoaiin.okol.oky.ocheo.r.okey.okeeo.l.cheo.o.****!.{Grove's C2}

All right. In Tahakari, this word is pronounced as koiin. But it doesn't sound much like koiin or other words.
