grow = grəu grew = gruː grown = grəun

Pronouncing English words can be almost as difficult as spelling them! The "ow" in "grow" is pronounced as "oh", as in "Oh my! What have you done?" And then there is the completely different sound of "ow" in "allow" and "cow". To make matters worse, you have the same spelt word, which has different meanings and spellings! : "bow" (same sound as "grow"): "The little girl carefully placed the bow on the wrapped package." "bow" (same sound as "allow"): "Unaware of the customary bow, the American made everyone uncomfortable during his visit to Japan by patting people on the back, shaking hands, and even slapping their hands while saying 'slap me five!'"
