* To urge on: There are no exact homophones for this phrase. However, "to urge on" could be confused with "to urge *awn*", which sounds very similar but is grammatically incorrect.
* Power of seeing things: The closest homophone is "power of seaing things", which uses the word "seaing" instead of "seeing". This is not a standard word in English but could be mistaken for "seeing" if spoken quickly or carelessly.
It's important to note that true homophones sound exactly alike but have different meanings and spellings. The examples above are not true homophones as they differ in spelling and pronunciation, but they could be confused in spoken language.
