“Unattached” Clauses in Technical Writing

The views concerning “dangling participles” of grammarians, usage experts and authors of books on technical writing are reviewed and compared. Although many unattached clauses are clearly unacceptable, some are less objectionable and still others are acceptable practice. Absolute constructions and other clause-relational participial, infinitival and verbless clauses need no attachment to a proximate noun or noun phrase, and logical clauses that are not attached to a noun are shown as normal, acceptable use. Even clearly adjectival clauses are often unattached when followed by the passive voice, intransitives and several other grammatical structures; clauses between the subject and verb and at the end of the sentence are also often not attached to the immediately preceding noun. Cultural (perhaps also gender) differences between humanistic teachers and task-oriented engineers are noted as possible causes of different viewpoints regarding the use of unattached participles, and greater acceptance of the many acceptable forms of unattached clauses is argued.
