In one sentence

A fronted adverbial is an adverb-like word or group of words moved to the front of a sentence, before the main clause, and followed by a comma.

Explained

An adverbial does the job of an adverb: it adds information about the verb, saying how, when, where, why or how often. It can be one word (Suddenly), a phrase (In the dark forest) or a whole clause (As soon as the bell rang).

Usually adverbials come after the verb: The owl hooted later that night. Move it to the start and it becomes fronted: Later that night, the owl hooted. The meaning is the same, but the emphasis shifts, and the sentence opens with atmosphere instead of a subject.

Fronted adverbials are useful for:

  • time: At midnight, Early the next morning, After a while,
  • place: Under the stairs, Far away, Behind the curtain,
  • manner: Without a sound, As quickly as she could, Carefully,
  • frequency: Every Saturday, Once in a while,
  • reason or condition: Because of the storm, If it rains,

In schools in England, put a comma after a fronted adverbial: Without warning, the lights went out. Published writers sometimes skip it after a very short one, but the comma is expected in school work and almost always helps.

"Fronted adverbial" is a term from the national curriculum in England (Year 4). In the US the same idea is usually taught as an introductory word, phrase or clause, with the same comma rule.

  • moon
  • owl
  • clock
Later that night, under a silver moon, the owl hooted.

Examples

Fronted adverbial Rest of the sentence Tells us
Yesterday, we planted beans. when
In the corner of the room, a spider spun its web. where
With a deep breath, Nadia stepped onto the stage. how
Because of the snow, school closed early. why
When the whistle blew, the players ran. when (a clause)

Common mistakes

  • Forgetting the comma. Later that day the dog escaped should be Later that day, the dog escaped.
  • Starting every sentence with one. Three in a row feels mechanical. Mix them with other openings.
  • Using a comma after the subject instead. The dog, barked loudly is wrong; nothing was fronted.
