"Blend of Anna and ly"
The name Annaly is commonly a female name from the "English" origin.
Annaly is a modern American formation rather than a name inherited from an older tradition. It joins Anna, a long-established given name, to the -ly ending that also closes names such as Annalee and Brynlee, and it first appears in United States birth records in 1990. The spelling is also consistent with Annalie and Annalee, but no earlier documented use of this exact form is known.
The pronunciation of Annaly is AN-uh-lee.
