Usage notes

Some authorities proscribe the comparative and superlative forms "more perfect" and "most perfect", on the grounds that perfection is an absolute state. Nevertheless, graded forms have been in common use in writing for centuries – for instance the Preamble to the United States Constitution, drafted in 1787, describes its goal as "a more perfect Union". In these cases, "more perfect" can mean "closer to perfection", "less imperfect" or "improving upon an already perfect state".
