subject – auxiliary inversion
When we use a particular group of words (called negative adverbials or limiting adverbials) we need to remember to invert the subject and auxiliary verb that follow.
Not once did they invite me to their house. – adverbial + auxiliary verb + subject + main verb etc..
These inversions can be used in writing to give a more formal air to the piece.
- On no account should you drive while taking these pills. Not only will they make you feel drowsy but they can also affect your vision.
They can also be used more informally in speech and writing for emphasis or to add dramatic effect.
- Only now do I understand how important a man my Grandfather was.
- Boy, can she be annoying!
Here is a list of phrases that require inversion:
Not only …. but also ….
