"living in the blood" (as a parasite does), by 1889, from Latin sanguis "blood" (see sanguinary) + colere "to inhabit" (see colony). Also, with classical stem, sanguinicolous.

late 13c. distourben, "to frighten, alarm, break up the tranquility of;" c. 1300, "to stop or hinder;" from Old French destorber (Old North French distourber) and directly from Latin disturbare "throw into disorder," from dis- "completely" (see dis-) + turbare "to disorder, disturb," from turba "turmoil" (see turbid). Related: Disturbed; disturbing; disturbingly.

Middle English also had the verb as distourblen, from Old French destorbler; hence also distourbler (n.) "one who disturbs or incites" (late 14c.).

"descended from a common ancestor," c. 1600, from French consanguin (14c.), from Latin consanguineus "of the same blood," from assimilated form of com "with, together" (see con-) + sanguineus "of blood" (see sanguinary).

also sangfroid, "presence of mind, coolness, mental composure," 1712, from French sang froid, literally "cool blood," from sang "blood" (from Latin sanguis; see sanguinary) + froid "cold" (from Latin frigidus; see frigid). "In the 17th c. the expression was in France often written erroneously sens froid, as if it contained sens "sense" instead of the homophonous sang "blood'." [OED].
