Funny story: swim

We were looking at a few verbs today, like ‘take, took, taken’ and ‘drink, drank, drunk’, and one of my students suddenly said ‘swim, swim, swimming’! And it made me think. Why are English verbs so difficult? If my students answer was the real answer then it would be so much easier.

BTW the answer is ‘swim, swam, swum’, unfortunately.

And here's a nice picture of an octopus swimming
