Here's why:
* The vowel sound in "finish" is short. It sounds like the "i" in "bit," not the long "i" sound in "bike."
* Long vowel words typically have a vowel sound that is pronounced the same as its letter name. For example, "bike" has a long "i" sound, "tree" has a long "e" sound, and "boat" has a long "o" sound.
