The word “chez” is a useful word in French, but we don’t really have an equivalent in English. It comes from the old Latin word “casa”, which means “house”.

You can use “chez” to mean either “the house of”, “at the house of” or “to the house of”

chez Pierre – Pierre’s house
chez moi – my house
je suis chez moi – I’m at home
je suis chez Pierre – I’m at Pierre’s house
je voudrais aller chez Marie – I would like to go to Marie’s house

You can also use the word “chez” in front of certain professions to mean ‘at the place” where they work.

chez le boucher – at the butcher’s
chez le médecin – at the doctor’s

je vais chez le coiffeur – I’m going to the hairdresser’s
il est chez le dentiste – he is at the dentist’s

If you use “chez”, you should always use the actual word for the person who does the job rather than the place they work. For example, “le boulanger” means “the baker”, and “la boulangerie” means “the bakery”.

chez le boulanger – this literally means “at the place of the baker”

If you want to use the place name instead, you can use the word “à” to mean “at” or “to”.

je vais chez le boulanger – I’m going to the baker’s
je vais à la boulangerie – I’m going to the bakery

je suis chez le boucher – I’m at the butcher’s
je suis à la boucherie – I’m at the butcher’s shop
