Again, a bad article. What's the difference between 1)a join 2) a joint 3) a bond? I don't know where to put translations. Someone, please expand this with usage examples. --Vahagn Petrosyan 04:12, 6 July 2009 (UTC)

A join is very unusual. Join is normally a verb. But as a noun, a join is a seam (where two pieces are connect with something such as glue, cement, or grout), or in mathematics it means a union or a logical sum, the sum of the elements of two or more sets.
A bond is the connection between two friends, or a man and his wife, or molecular bonds that hold molecules together. A bond can also be a glued or cemented joint between two surfaces.
A joint usually can be articulated, as a knee joint or finger joint, or a point of articulation between two sections. Joint is the most general noun, join is usually the verb, and bond is more figurative. —Stephen 05:16, 6 July 2009 (UTC)
