What are repetitions of units consisting of two or more words (e.g., 'Mommy's home‒mommy's home to make dinner') called?

Repetitions of units that consist of two or more words, such as "Mommy's home‒mommy's home to make dinner," are known as phrase repetitions. This term specifically refers to the repetition of short phrases or groups of words as opposed to single words or longer sentences. Recognizing the nature of these repetitions is important in understanding communication patterns, especially in contexts such as language development or speech disorders, where evaluating the frequency and type of repetitions can provide insights into a person's communicative abilities and challenges.
