Usage
A few usage guides still object to the use of comparison words such as more, most, nearly, almost, and rather with perfect on the grounds that perfect describes an absolute, yes-or-no condition that cannot logically be said to exist in varying degrees. The English language has never agreed to this limitation. Since its earliest use in the 13th century, perfect has, like almost all adjectives, been compared, first in the now obsolete forms perfecter and perfectest, and more recently with more, most, and similar comparison words: the most perfect arrangement of color and line imaginable. Perfect is compared in most of its general senses in all varieties of speech and writing. After all, one of the objectives of the writers of the U. S. Constitution was “to form a more perfect union.” See also complete, unique.
For most of its meanings, the adjective perfect describes an absolute state, i.e. one that cannot be qualified; thus something is either perfect or not perfect, and cannot be more perfect or less perfect. However when perfect means excellent in all respects, a comparative can be used with it without absurdity: the next day the weather was even more perfect

Etymology
Origin of perfect
First recorded in 1250–1300; from Latin perfectus “finished,” past participle of perficere “to finish, bring to completion,” from per- per- + -fecere, combining form of facere “to do, make” ( see also do 1); replacing Middle English parfit, from Old French, from Latin, as above
Explanation
Something that is perfect is complete and without defect or blemish. It might also be precisely accurate or exact. The word perfect can also be used as a verb meaning — you guessed it! — to make something perfect. (Note, though, the pronunciation difference: PER-fect as a noun; per-FECT as a verb.) It originally comes from the Latin word perficere, which breaks down into per- ("completely") and facere ("do"). As a noun perfect is a grammatical term referring to a tense of verbs describing an action that has been completed.
