Does the words leash and goose have long e sound?

You're right to think about the "ee" sound! Here's how it breaks down:

* Leash: The "ea" in "leash" makes a long "e" sound, like in "see" or "tree".

* Goose: The "oo" in "goose" makes a long "oo" sound, like in "moon" or "food".

So, while both words have a long vowel sound, they're different long vowel sounds.
