We’re on the second sentence in 14th Conlang Relay text:

sanna jasāla jīsōra ke þō lisōra;

þō here is acting as a definite modifier “this” or “these”. þō is also a particle meaning “here” or “this place”. Here, however, it has to be the first þō because it is part of the source phrase headed by ke.

Tomorrow I will discuss lisōra.
