I finished solving a cryptic crossword yesterday. One of the answers was APERITIF.
A few minutes later a friend came round for the evening. I made her a cup of tea. We would be having a meal together later but she asked if she could have a square of my dark chocolate as an APERITIF. She had misused the word and it was the first time in the 46 years that I have known her that I have heard her use it!
