I have hidden something from my nemesis Aufero inside other words. The rules are that I can only add one or more letters to a word inside that word (not at the beginning or end), I can only add a single string of letters, and both words must be valid.
For example, I can turn actuate into accentuate, but I cannot turn scribe into describe, or mount into monument. Word pairs such as actuate-accentuate are called auferonyms.
I have taken the letters of the the secret word and hidden them inside the following words. Aufero only knows that my secret has something to do with an upcoming wedding.

What am I hiding from Aufero?
