Have you noticed how often people use redundant phrases without even realizing it? Here are a few examples.

• ATM Machine – Since ATM stands for Automatic Teller Machine, the incorrect version is actually saying Automatic Teller Machine Machine.
• PIN Number – Similarly, a PIN is a Personal Identification Number, so it’s unnecessary to add an extra “number” at the end.
• Hot Water Heater – As opposed to the cold water heater? Jenny used to work for a plumbing company, and apparently plumbers HATE this one.
• Tuna Fish – I’d rather have the tuna chicken, thanks.
• Cease and Desist – Can I cease and persist instead?
• Please RSVP – RSVP is an abbreviation for the French phrase repondez s’il vous plait or literally respond if you please.
