What is the difference between Lord Datta and Lord Dattatreya?

[An online spiritual discussion was conducted on March 13, 2021, in which several devotees participated. The questions of devotees answered by Swāmi are given below.]

[A question by Kum. Laxmi Thrylokya.]

Swāmi replied: Datta means the first Energetic Incarnation of the unimaginable God given to the world for meditation and worship. Dattātreya is the Human Incarnation born to Sage Atri and Anasūya in whom God Datta merged. Dattāreya is a later Human Incarnation of God Datta.
