German budget supermarket Aldi is so engrained into Brits' lives that they didn't even realise the name is actually short for something.

The first Aldi store opened in Birmingham in 1990, so it's easy to forget that it's not actually a British store, and doesn't have a British name. It's not like Asda, a British supermarket chain which stands for Associated Dairies.

It turns out, despite being around for more than 30 years, people are only just realising what Aldi's name stands for. Aldi originated in Essen, Germany, when Anna Albrecht opened a small grocery store in 1913 – which gives you half of the name.

When her two sons, Karl and Theo Albrecht, came back after fighting in World World II, they took over the store, and they expanded to more than 100 stores in 1955.

They proved popular by keeping prices low, which they were able to do by not spending money on advertising, which gave them an edge in the post-war economy. By 1962 there were more than 300 stores.

Aldi stands for Albrect-Diskont, which in English means Albrecht's Discount, which is a name the brothers introduced in 1961. They eventually took the two first letters of each word to form Aldi, which is pronounced All-Dee.
