Hebrew

יָשָׁן • (yashán) (feminine יְשָׁנָה, masculine plural יְשָׁנִים, feminine plural יְשָׁנוֹת)

This adjective is never used to refer to an elderly person or an old animal. In that specific sense the adjective זָקֵן (zakén) is used instead.

יָשַׁן • (yashán) third-singular masculine past (pa'al construction, infinitive לישון / לִישֹׁן, present יָשֵׁן, future יִישַׁן, imperative יְשַׁן)

to sleep, to be asleep
- Tanach, Psalms 121:4, with translation of the New International Version:
  הִנֵּה לֹא־יָנוּם וְלֹא יִישָׁן שׁוֹמֵר יִשְׂרָאֵל.
  hiné lo yanúm vəlo yishán shomér yisraél.
  Indeed, he who watches over Israel never slumbers or sleeps.
