Philology

Some words I like:

obsolete (it sounds so clean and soapy, like we've washed away a need)

crisp (almost time for apples and fall air)

leafy (strikes me as almost onomatopoeic, the sound of a summer breeze through a full tree: leafffffy)

nail (metallic and to-the-point)

perfect (it's a perfect word, precise and resolute, satisfyingly chewy)
