Bonjour Kathleen,

Thank you for excellent question.

When ‘aussi’ is an adverb (as in meaning ‘also / too’ or ‘in addition’) it is placed following the word (verb / noun) it is referring to:

Sophie viendra aussi = Sophie will come too

Antoine est venu et Sophie aussi = Antoine came and Sophie too

Le nouveau budget prévoit une réduction d’impôts. Il prévoit aussi une augmentation de salaire = the new budget provides for a tax reduction. It also (in addition) provides for a salary increase

I hope this is helpful.

Bonne journée!

Bonjour Stephanie,

Antoine est aussi venu = Antoine came too

Antoine est venu aussi = Antoine came too -> familiar / everyday 

 

Attention: here it is a conjunction not an adverb (implies a consequence or an explanation)

Aussi, il est venu = as such (as a consequence) he came 

 

I hope this is helpful.

Bonne journée !
