differences Is it flotation or floatation English The spelling flotation is not etymologically justifiable but is more common in use probably because it disguises the hybrid formation so that the word appears more conformable to the general analogy of scientific terms improve this answer edited Sep 29 12 at 18 13 75 silver badges 125 bronze badges answered Sep 29 12 at 18 10
