Abstract:

This article begins by arguing that the infinitive phrase has not been taken seriously in writing because writers have been too concerned with Bishop Robert Lowth's proscription against the split infinitive. However, careful examination of three types of technical prose (instructions, annual reports, and 'junk mail') reveals that more than one sentence in four contains an infinitive phrase. The article then argues that two linguistic theories do not adequately explain the overwhelming presence of infinitives in the three types of prose. The reason for the presence of infinitives seems to be that they fulfill several rhetorical purposes, including vigor, symmetry, emphasis, variety, economy, and depersonalization. Implications for writing and teaching are also discussed.
