translate English to French: This is not to say that language is unimportant (as the tone and energy of conversations would deny anyway), but rather that it seems to be important for different, more practical and more personal reasons.
Cela ne veut pas dire que la langue n'est pas importante (le ton et l'énergie des conversations le nient), mais elle semble importante pour des raisons différentes, plus pratiques et plus personnelles.
