"Blend of Bryn and Lee"
The name Brynlee is commonly a female name from the "American" origin.
Brynlee is a modern American formation built from two name elements: Bryn, a Welsh name taken from the Welsh word bryn, meaning hill, and the ending -lee found in names such as Kaylee and Bailee, which goes back to Old English leah, a woodland clearing. The two parts are both long established in English-language naming, but the combined form Brynlee is not a traditional given name in Welsh or English usage.
The pronunciation of Brynlee is BRIN-lee.
