jakēþa
The fifth sentence of the 2nd Inverse Relay text:
selte jālme japāsre to jakēþa jatāra;
jakēþa is a type of plant, specifically something like a large tree, one that is mostly trunk, and so the word can also refer more generally to a tree trunk. jatāra is the inanimate singular form of the familiar antāra “fallen”. So, jakēþa jatāra is a fallen trunk.
selte jālme japāsre to jakēþa jatāra;
We experience a hindered fording due to a fallen tree trunk.
