Here’s an example of how the German language can be very specific. These are all the variations of the German verb ‘kann’.

kann, kannst, können, könnt, konnte, konntest, konnte, konnten, konntet, gekonnt

You pick the form depending on who and when you say it. Pretty much every verb is like this. Kids here can figure it out. Many of those kids grow up to be brilliant engineers.
