A male person who has the same father and mother with another person, or who has one of them only. In the latter case he is more definitely called a half brother, or brother of the half blood. Note: A brother having the same mother but different fathers is called a uterine brother, and one having the same father but a different mother is called an agnate brother, or in (Law) a consanguine brother. A brother having the same father and mother is called a brother-german or full brother. The same modifying terms are applied to sister or sibling.

[1913 Webster] Note: In Scripture, the term brother is applied to a kinsman by blood more remote than a son of the same parents, as in the case of Abraham and Lot, Jacob and Laban. In a more general sense, brother or brethren is used for fellow-man or fellow-men. [1913 Webster] For of whom such massacre Make they but of their brethren, men of men? --Milton. [1913 Webster] Brother Jonathan, a humorous designation for the people of the United States collectively.

Easton's 1897 Bible Dictionary:

Brother (1.) In the natural and common sense (Matt. 1:2; Luke 3:1, 19). (2.) A near relation, a cousin (Gen. 13:8; 14:16; Matt. 12:46; John 7:3; Acts 1:14; Gal. 1:19). (3.) Simply a fellow-countryman (Matt. 5:47; Acts 3:22; Heb. 7:5). (4.) A disciple or follower (Matt. 25:40; Heb. 2:11, 12). (5.) One of the same faith (Amos 1:9; Acts 9:30; 11:29; 1 Cor. 5:11); whence the early disciples of our Lord were known to each other as brethren. (6.) A colleague in office (Ezra 3:2; 1 Cor. 1:1; 2 Cor. 1:1). (7.) A fellow-man (Gen. 9:5; 19:7; Matt. 5:22, 23, 24; 7:5; Heb. 2:17). (8.) One beloved or closely united with another in affection (2 Sam. 1:26; Acts 6:3; 1 Thess. 5:1). Brethren of Jesus (Matt. 1:25; 12:46, 50: Mark 3:31, 32; Gal. 1:19; 1 Cor. 9:5, etc.) were probably the younger children of Joseph and Mary. Some have supposed that they may have been the children of Joseph by a former marriage, and others that they were the children of Mary, the Virgin's sister, and wife of Cleophas. The first interpretation, however, is the most natural.
Bouvier's Law Dictionary, Revised 6th Ed (1856):

BROTHER, domest. relat. He who is born from the same father and mother with another, or from one of them only. 2. Brothers are of the whole blood, when they are born of the same father and mother, and of the half blood, when they are the issue of one of them only. 3. In the civil law, when they are the children of the same father and mother, they are called brothers germain; when they descend from the same father, but not the same mother, they are consanguine brothers; when they are the issue of the same mother, but not the same father, they are uterine brothers. A half brother, is one who is born of the same father or mother, but not of both. One born of the same parents before they were married, a left-sided brother; and a bastard born of the same father or mother, is called a natural brother. Vide Blood; Half-blood; Line; and Merl.
