I see so would you refer to a training session as a tarbiiyatii daur or a tarbiiyatii ijlaas? I'll give a few examples of sessions that we may come across on now and then. To keep things interesting some will be whimsical and I want to see which term you would opt for in each.
Debating session- I would suggest BeHs-mubaaHisa Ijlaas or MubaaHisa ijlaas.
discussion session- Guft-u-guu Ijlaas or BeHsii Ijlaas.
Q&A session- Su'aal-Jawaabii Ijlaas
Kissing Session- Bos-aa-Bosii nishast/baiThak/ijlaas/daur?
Training Session- Tarbiiyatii-daur, Tarbiiyatii-mashk, Mashkii-daur. Daur e tarbiiyat o mashk, Mashk o tarbiiyatii daur.
Coaching Session- Tadreesii-mashk, Tadreesii-daur, Tadreesii-ijlaas (if it involves being seated).
Sex Session- No idea but I would be curious as to what others suggest. I would hazard a guess with Jinsii-ijlaas or Jinsii-daur...
Exercising Session- Warzishii-waqt, warzishii-seshan, warzishii-daur, warzishii-mashk, warzishii-ijlaas?
Yoga Session..
So the operative question here being do you have to be seated for it to be an Ijlaas or like a Jalsa that no longer is the pre-requisite? Now in Arabic, it doesn't matter and the term jalsat is used universally, as a synonym for its English equivalent.
Would love to see what Perso-phones use as well.
For all of these, the word Seshan i.e. session can also practically be used.
