Middle Name Meanings
The Sentimental Meaning
Most often, middle names are chosen based on their sentimental meaning. The sentimental meaning of a name can be what the name "means" to the parents. For instance, a couple may have conceived their baby at a certain place, so the name of that place could become the foundation of their baby's name. As an example, a couple may have conceived their baby in Hawaii, so they may choose a Hawaiian name for their baby's middle name.
Couples may also choose a middle name that symbolizes their family's lineage. For example, couples with a Scottish heritage may choose to give their child a middle name such as Sinclair (the "clan" their ancestors were part of) to represent the family heritage.
In other cases, some people choose a middle name in honor of a special person in their life. That way, as they reflect on their child's name, the person that was dear to them will come to mind. By naming your child after someone who has made a difference in your life can be one of the best ways to show your thanks and appreciation to someone who was inspirational to you -- a way of telling them that you hope your child's life will have the same kind of impact on someone else as they had on yours.
