I prefer the term they now use, enriched air.
Yea, that's as good as, or better, term than any.
Although in the early daze in Oz they (or should I say ANDI) called it 'Safe Air' which if the truth be known, it was anything but in the circumstances that prevailed in Oz back then. And especially so to new nitrox divers, especially with so little widespread easily accessible info out there - and the judgement / perception of the overall diving community being that it was the 'devils gas' anyway, it was anything but 'safe' air (as regards depth limits, dive tables, O2 'cleaned' cylinders being necessary, etc. - as all blending / mixing being O2 in first, then topping with air).
