What english word retains the same pronunciation, even after you take away four of its five letters?

“Q”

While 'Q' is pronounced the same as 'queue', it does not fit the criteria of being an English word with four letters removed, as 'Q' itself is just a single letter.

“Knew”

'Knew' does not retain the same pronunciation when you remove any of its letters; it changes drastically, making it an incorrect answer.

“Blue”

Removing letters from 'blue' does not yield a word that retains the same pronunciation; the sounds change significantly with each removal.
