Lady - Vine's Expository Dictionary of New Testament Words
Lady
[ 1,,G2959, kuria ]is the person addressed in 2 John 1:1, 2 John 1:5. Not improbably it is a proper name (Eng., Cyria"), in spite of the fact that the full form of address in 2 John 1:1 is not quite in accord, in the original, with those in 2 John 1:13; 3 John 1:1. The suggestion that the church is addressed is most unlikely. Possibly the person is one who had a special relation with the local church.
