Does insane have a short vowel sound?

No, "insane" does not have a short vowel sound. It has a long "a" sound, similar to the "a" in "say".

Here's why:

* Spelling: The "a" in "insane" is followed by a single consonant ("n") and then a silent "e" at the end. This is a common pattern for long vowel sounds in English.

* Pronunciation: When you pronounce "insane", the "a" sound is drawn out, not short and clipped.
