jalātaren
This is the word for south-east. It might be derived from -lāj- ‘mountain’. Unlike the other direction words, this one has a slightly irregular paradigm. Most of the direction words vary between a form that ends with -ien and a form that ends in -ie. The nouns, both singular and stative, use the -ien form, as does the sū- form. The rā- and rū- forms use the -ie form. For example, using yesterday’s word:
jahāwien the south-west
sūhāwien at or in the south-west
rāhāwie to the south-west
rūhāwie from the south-west
With today’s word the forms are: jalātaren, sūlātaren, rālātie, rūlātie. I have no idea where that -r- came from, nor where it went.
