Cách sử dụng
The word 'umbilical' refers to something that is related to or connected with the belly button. It is often used in medical contexts, such as when talking about the umbilical cord that connects a baby to its mother during pregnancy. However, it can also be used in a more figurative sense to describe a strong or close connection between two things or people, much like how an umbilical cord connects a mother and her child. For example, you might say that a company has an umbilical relationship with its customers, meaning that they are very closely connected and dependent on one another.
