Did you know there are over a hundred different species of birds in this park?

Really? I had no idea it was that diverse.

Root Explanation

Hundred originates from Old English 'hundred' (meaning a group of one hundred). The word is derived from Proto-Germanic '*hundwurtiz', which is a compound of 'hund' (meaning ten) and 'wurt' (meaning group or set).

Memory Tip

Think of a 'group of ten' ('hund') multiplied to make a 'hundred' — that's how you can remember that 'hundred' means a set of one hundred.
