Making an impression is a common goal for many people, whether it be in the workplace or in social situations. Etching, sealing, denting, registering, aping, and striking home are all ways to make an impression. Etching is the process of carving a design into a hard surface, such as metal or stone. Sealing is the act of closing something off with a wax or adhesive material. Denting is the process of making an indentation in a surface. Registering is the act of officially recording something, such as a trademark. Aping is the act of imitating someone or something. Finally, striking home is the act of making a strong impression on someone.
