Dangling “followed”

Pick up any usage book and you’ll be sure find a discussion of dangling participles. Participles are formed from verbs but act as adjectives, and as such, they require an appropriate noun to modify. When they fail to meet this requirement, they are said to dangle. Here, I’m going to focus on a specific participle that often dangles in scientific writing: the past participle “followed.” Let’s look at some sentences.

Metal precursors were introduced into separate polymer blocks, followed by removal of the templates by pyrolysis.

The author intended “followed” to modify a noun that doesn’t actually appear in the sentence, “introduction”:

Adverb placement: Predominantly, mainly, mostly

The placement of adverbs—which modify verbs, adjectives, or other adverbs—can substantially change the meaning of a sentence. You’ve probably run across example sentences illustrating the importance of correctly placing the adverb “only”:

I drive only red cars; I do not drive green cars.

I drive red-only cars; I do not drive multicolored cars.

I drive red cars only; I do not drive red motorcycles.
