Why does the o in word some make u sound?

The "o" in the word "some" doesn't actually make a "u" sound. It makes a short "u" sound, which is different from the long "u" sound in words like "flute" or "cube".

The short "u" sound is often represented by the letter "u" in words like "cup" or "sun", but it can also be represented by other letters, like "o" in "some", "son", or "love".

This is because the sound of a vowel can be influenced by the surrounding letters and the pronunciation of the word.
