figure of speech?: "inextricabilem intricationem"


New Member
I came across the phrase "inextricabilem intricationem" recently and I wanted to describe the kind of almost-rhyme that happens here ("inextrica-/intrica"), where both words start the same way, but with an extra syllable added in one. I don't know how to describe it except "almost rhyme" or "wordplay" (or maybe I could call it morphological wordplay?). Does anybody have good ideas for how to talk about this effect?
