Ik = I
Hij = he
Zij = she
Wij = we
Let's Take the verb "hoor" which means "hear."
Ik hoor
Hij hoort
Wij hooren
By this you can deduct this rule:
Hoor is the foundation and used with Ik.
Hoor + t = Hoort and is used with Zij and Hij.
Hoor + en = Hooren and is used with Wij.
You can do the same with "zeg" which means "say."
Ik zeg.
Zij/Hij zegt. (+t)
Wij zeggen. (+en)
