Which one is the short U sound and which long sound?

You're asking about the vowel sounds in English, which can be tricky because the same letter can represent different sounds.

Let's break it down:

"Short U" sounds like the "u" in words like:

* "cup"

* "sun"

* "duck"

"Long U" sounds like the "u" in words like:

* "cube"

* "flute"

* "music"

Important Note: The "long u" sound is actually represented by the letter "u" followed by a silent "e" at the end of the word (like in "cube"), or by a combination of letters like "ue" (like in "flute").
