Etymology: "Used" is a plain inflected form, so its history is simple. It comes from the verb "use," with the ending "-ed" added to show past participle or adjectival status. The adjective senses (worn out, accustomed, put to a purpose) developed from that participle, which is why one word covers both "a used car" and "I am used to the cold."
