The semicolon is often left out because the writer is unclear on how to use it. In other cases, the semicolon gets used when a simple period would suffice. In technical writing, the semicolon can be a powerful tool but it can also hinder effective writing. Let’s look at a couple examples.
Two Complete Sentences
The VMS does not remotely control the feeder. The Transformer feeder operates either autonomously or via manual control at the feeder door.
One Combined Sentence with a Semicolon
There is no remote control of the feeder from the VMS; it operates autonomously or via manual control at the feeder door.
In the second example, the semicolon tightens up the sentence while still presenting both ideas. This reduces the word count slightly, but if used too often it will give our writing a run-on sentence feel.
The period in the first example separates the two ideas but still keeps them close. This is the wordier option but it gives more attention to each concept by bringing the reader to a stop between them.
There are many grammatical tools to help us connect to our audience with our writing and steer them toward understanding. If you are unsure about a particular tool, research it and practice with it, or ask a member of the technical writing team.
