Abbreviations in Kurdish Kurmanji 506670 - what do they mean?

In the Kurdish Kurmanji course (506670) there are abbreviations in brackets after some words.
I am (cons.)
You are (sing., cons)
How are you? (pl.)

I know that:
sing = singular (one person)
pl = plural (more than one person)

  1. What does “cons” mean?
  2. Are there other abbreviations that I will encounter?

Thanks - I love that there is an app helping me learn Kurmanji.
If I can help in any way (native English speaker/teacher/IT/Yazidi friends), please let me know.
