Constant Repeating of Words in My Head - Echolalia?

Autism and echolalia? I feel like i might have some sort of echolalia, but it’s not like I repeat out loud, its like a constant repeating of a random word (honestly I did this with the word echolalia too) in my head that plays on repeat all day long or for a few hours. It’s like getting a song stuck in your head but its a word or phrase, my most recent one was the word rutabaga because I found it strange. I will change the pronunciation after a little while when it’s stuck in my head or maybe add an accent. It’s very interesting and I would like to know if anyone else does the same thing!
