Where to put "aussi" when using the passé composé
J’ai aussi acheté les billets d’avion.
J’ai aussi écrit deux guides.

If you want to use "aussi" together with the passé composé, is it required or customary to put "aussi" between the avoir/être auxiliary verb and the past participle, as in the above sentences?  Or can "aussi" go in other places in the sentence?

Answer

The form you used is the most common, you can also put "aussi" at the end of the sentence, to insist on it :
"J'ai écrit deux guides aussi."

But if you place it at the beginning of the sentence, the meaning change :
"Aussi j'ai écrit deux guides."
Here, aussi means "that's why"
