The piling up of modifiers before a noun. Because clarity may be sacrificed for conciseness, stacked modifiers are generally considered a fault, especially in technical writing.
Examples and Observations:
- Stacked modifiers are strings of modifiers preceding nouns that make writing unclear and difficult to read.
- Your staffing-level authorization reassessment plan should result in a major improvement.
- Your plan for reassessing the staffing-level authorizations should result in a major improvement.
- Be careful of stacked modifiers (adjectives and adverbs). . . . Be especially careful of cases in which the first descriptor could modify either the second descriptor or the noun. For example, what exactly is a "buried cable engineer"? (And how does one breathe?)
(Edmond H. Weiss, 100 Writing Remedies, Greenwood, 1990) - Stacked phrases range all the way from supposedly simple combinations like "the then district attorney" to complex combinations like "the Halloween-night multiple-gunshot killing of a 30-year-old woman."
The "then district attorney" is presumably a person who was district attorney at that time, and the murder must have occurred on Halloween night when someone shot a 30-year-old woman several times. . . .
Newswriters who adopt this technique sacrifice clarity and may not save time. . . . Concise prepositional phrases and subordinate clauses are usually more neutral.
