*merg-

The original sense of this root was:

boundary, border

Over time, a sizable part of the family tree has shifted toward the “markings” that show the boundary and many of the offsprings today are about the general idea of marking.

Notable English members of this family are:

• the mark (a marking)
• the march (the boundary of a country, NOT the walking style)
• the margin (a boundary of sorts)
• marquis
• remark  (and friends)
