Is this assonance: "I was excited, delighted, and filled with glee."?
Assonance is the use of repeated vowels close enough together to be noticed.
In this case, the "I" of "excited" and "delighted" certainly are assonance.
There is another assonance in there as well but is more hidden - the "E" of the first syllable of "delighted" and "glee".
