  • (v. t.) A very small quantity of an element or compound in a given substance, especially when so small that the amount is not quantitatively determined in an analysis; -- hence, in stating an analysis, often contracted to tr.
  • (v. t.) A mark, impression, or visible appearance of anything left when the thing itself no longer exists; remains; token; vestige.
  • (v. t.) The intersection of a plane of projection, or an original plane, with a coordinate plane.
  • (v. t.) The ground plan of a work or works.
  • (v. t.) To mark out; to draw or delineate with marks; especially, to copy, as a drawing or engraving, by following the lines and marking them on a sheet superimposed, through which they appear; as, to trace a figure or an outline; a traced drawing.
  • (v. t.) To follow by some mark that has been left by a person or thing which has preceded; to follow by footsteps, tracks, or tokens.
  • (v. t.) Hence, to follow the trace or track of.

  • (v. t.) To walk over; to pass through; to traverse.
  • (v. i.) To walk; to go; to travel.

Tracing


Definition:

  • (n.) The act of one who traces; especially, the act of copying by marking on thin paper, or other transparent substance, the lines of a pattern placed beneath; also, the copy thus producted.
  • (n.) A regular path or track; a course.
