You can take advantage of the similarities in sound between words in creating ambiguity. Phonological ambiguity is the uncertainty created by similar-sounding words.

“Can you be a good s(u)pport about this new plan?“ (Sounds like a good sport.)

“Relaxing from your head on down to your sole-s of your feet.” (Sounds like down to your soul, spelled s-o-u-l instead of s-o-l-e.)
