Here's why:
* Spelling: The word "see" has a double "e" at the end, which is a common indicator of a long vowel sound.
* Sound: The vowel sound in "see" is a clear, sustained "ee" sound, similar to the vowel sound in "tree" or "bee".
* Short vowel sounds are typically short and quick, like the "a" sound in "cat" or the "i" sound in "big".
So, when you say "see", you're making a long vowel sound.
