Uterine lyre is a term used to describe the shape of the uterus in certain animals, such as bovines. The spelling of this word can be a bit confusing, especially when it comes to the pronunciation. In IPA transcription, it is spelled as [juːtəraɪn laɪər], with the emphasis on the first syllable. The word "uterine" refers to the uterus, while "lyre" refers to the shape of the uterus resembling a lyre, a stringed musical instrument.
