Abstract
The practicing technical editor quickly realizes that regardless of author or subject, the same grammatical errors occur repeatedly in manuscripts. This can probably be blamed on a fundamental weakness in the training of technical writers, rather than on any lack of individual or collective ability on the writer's part. With this in mind, ten errors commonly found in technical manuscripts are collected and presented. It is hoped that the list will be helpful to teachers of technical writing and to technical writers who wish to improve their craft.
