Join and separate complete clauses

A complete clause has a subject and a finite verb. Two complete clauses need a valid boundary.

01 / THE METHOD

Make it repeatable

  1. Locate the subject and main verb on each side of the blank.
  2. If both sides are complete, use a period, semicolon, or comma plus a coordinating conjunction.
  3. If one side is incomplete, do not add a period.
  4. Read the completed sentence aloud to catch a comma splice.
02 / WORKED EXAMPLE

Watch the method in action

“The team collected samples ___ the lab analyzed them.”
  1. “The team collected samples” is complete.
  2. “The lab analyzed them” is complete.
  3. A semicolon or “, and” joins them correctly.

“The team collected samples; the lab analyzed them.”
