“This book is dedicated to XXX, without whom it would never have been started, and to YYY, without whom it would never have been finished.”
This is the acknowledgement of a book I took a look at today. I have seen some acknowledgements with “never have been started” or “never have been finished”. But not both. It sounds much more beautiful with both than each. It does not seem to be likely for me to have something to publish a book about under my name in my life.
