Is sew a short vowel sound?

No, "sew" does not have a short vowel sound. It has a long "e" sound, similar to the "e" in "see".

Here's why:

* The "e" at the end of the word "sew" is silent, but it changes the pronunciation of the "e" in the middle.

* Silent "e" at the end of a word often indicates a long vowel sound.

Therefore, the "sew" in "sew" sounds like "so" in "so" or "go" in "go".
