Archaic to whom? Is it the manner in which you speak in daily life? If so then people who know you, know your intent. Those who don't may be taken aback at first. Some may think you are talking down to them. Strive to be you not "posh" or fit in. Just speak the words that come naturally. Education isn't an embarrassment nor should it be used to make others feel small.
