The upper case is used in many English translations where the tetragrammaton appeared in Hebrew.

adonai or adonay is simply our English tongue pronouncing the Hebrew word for Lord.

Are you sure? Adonai is a Hebrew word and IS used in the OT when referring to Jehovah. The tetragrammaton JHVH is written as LORD in our English version bibles but both terms are used in the OT when referring to the one true God.

For example in Deut. 3:24, Adonai (Lord) is used referring to God- Jehovah. The word lord - adown - is used when referring to people as in a master. In Gen. 23:6, Sarah uses it referring to Abraham. In the KJV, Jehovah is written as LORD, adonai is written as Lord and adown is written as lord. At least that is what I learned.
