Apparently if you use these words it makes you middle class

We already know that if you have any of these items in your kitchen cupboard, it makes you middle class. But apparently there's more to it than swanky Nutribullets and posh square plates. According to one expert, there are certain words that make you middle class, too.

William Hanson, an etiquette expert and coach, told Cosmopolitan UK that vocabulary is an insight into someone's class - from Americanisms to abbreviations.

From shortened versions of words ('university' to 'uni' or 'avocado' to 'avo'), to formal greetings ('Pleased to meet you'), apparently what we say can indicate whether or not we're middle class - whether it's to do with food, films or Fitbits.

Apparently, the ten words that make you middle class are:

• Pardon?
• Toilet
• Pleased to meet you
• Bubbly or ‘Fizz’
• Kids
• Avo
• Movie
• Uni
• Booze
• "I’m done"
• Catchment area
• Fitbit
• Vegan

'Fitbit' seems like an unusual addition to the list, as does 'movie', but okay.

So all in all, if you have a Brita filter and you enjoy a glass of 'bubbly' or 'fizz', then there's no denying it any longer - according to the etiquette pro, you're middle class.

So now you know.
