To pronounce roughhewn, start with "ruff" (for rough) and add "hue" (like a 'hue' of red or a 'hue' of blue) and "n" to the end You'll have "ruff hue n" for roughhewn. If you need a little extra help, take the word "universe" and break it down into "syllables" (that aren't the "real" ones). You'll get "un" and "i" and "verse" when you do. Take the first syllable, add the letter "h" and you've got "hewn" down pat. Rough is still pronounced "ruff" like in the first example.
