How Do You Spell ENLARGED UP ON?
Pronunciation: [ɛnlˈɑːd͡ʒd ˌʌp ˈɒn] (IPA) 
The phrase "enlarged up on" can be slightly confusing when it comes to spelling. The word "enlarged" (ɪnˈlɑːrdʒd) is spelled with an "e" after the "g", while "upon" (əˈpɑːn) is spelled with a "u" after the "p". Moreover, the addition of "up" in the phrase makes it a little more challenging to spell correctly. Despite its complexity, "enlarged up on" (ɪnˈlɑːrdʒd ʌp ɒn) is a perfectly grammatical and widely used phrase in English.
