"This lion has been living in our yard for one week."

Translation: Ce lion habite dans notre jardin depuis une semaine.

"Has been living" cannot just be "habite"

[choracavaco]

It can. The 'present perfect continuous + for' tranlates to the French "présent + depuis". An action that started in the past but is still going on in the present is expressed in French with the present.

Should "il y a une semaine" or "pour une semaine" also work?
