I would like to know how to translate “so to speak” in French. So far, the only thing I can come up with is disons que.
"So to speak" means "pour ainsi dire".
The correct translation is
Façon de parler
Which would be the literal translation for “way to speak”.
Je suis bien meilleur joueur de tennis que lui, je vais le détruire ! Enfin, façon de parler.
«c'est à dire» would be the correct way if you think about how to convey the same idea (instead of word to word translation) from English to French.
