- This lecture is so boring.
- I am bored because of this lecture.
Well, similar difference between tired and tiring:
- The carrying of baggage up the room is tiring.
- It made me tired.
And why did I even start talking about this strange word, tiring, that isn’t used very often to begin with? Why, because of this joke, of course:
Tire = pneumatika
Tiring = “pneumatikování”, or, as mentioned above, something that makes you tired. Nice way to remember this, isn’t it?
