Grimm's Law and Verner's Law

Use the player below to learn or review the sound changes of Grimm's Law. The player controls work like those of a CD player: press the pause button if you'd like to stop the lesson and restart from the same place, or press the 'stop' button if you'd like to return to the beginning and play the lesson again.

There is an error that appears twice in the green explanatory text for step 4. Can you find it?

NOTE: some of the characters in the flash player that opens from the link below appear incorrectly in current browsers. If so, make the following mental substitutions: for capital T, read theta (θ); for capital B, read beta (β); for capital F read gamma (γ); for capital X read lower case x. Most of these errors are found in the step for Verner's Law.
