A word or phrase that normally comes after the verb may be moved before the verb: when this happens, we say it has been ‘fronted’. For example, a fronted adverbial is an adverbial which has been moved before the verb. When writing fronted phrases, we often follow them with a comma.
- Before we begin, make sure you’ve got a pencil. [Without fronting: Make sure you’ve got a pencil before we begin.]
- The day after tomorrow, I’m visiting my granddad. [Without fronting: I’m visiting my granddad the day after tomorrow.]
