The world is a global village where there are no clear cut boundaries of ‘what is mine’ and ‘what is yours’. There is no pure nation that caters only to one ethnicity or culture. Culture is a creation of man for man and it changes its form and shape with time and need. Each culture brings with it something to enrich the society in which they live. And as civilizations progress and mankind realizes the true meaning of co-existence the boarders that marked and distinguish each society from that of another slowly merges in to a vague blur of diversity. Each culture learns to borrow from another culture while giving something back to them from their own culture. This sometimes can happen voluntarily but the truth be told most of the time this happens involuntarily and this interchange goes so far back and forth that no one remembers or knows where that specific part of the culture came from. Each culture contributes a specific aspect and at one point it becomes a masterpiece of culture that has no artist owner, check this awesome European grocery store.
Let me explain this by taking an example from our day to day lives. What the Germans called ‘Delicatessen’ has expanded horizons and has been accumulated in to different cultures and societies with little changes yet preserving the essence of it. You may have heard of it or even dined in these kind of shops all the time. The word simply is used to denote a retail outlet that sells varieties of prepared foreign food and delicacies. Even though the establishment originated in Germany (Started with Dallmayr which was a German business/company that specialized in importing foreign food like plums from places like China and Cannery islands which is said to have originated in the 1700’s ) when the German Jews fled to United States they took this culture with them.
Even though it originated in Germany the word itself is borrowed from the French which is said to mean delicious edible things. However its root word is borrowed again from Latin meaning roughly something that gives pleasure. When the Americans adopted this they shortened the word to mere ‘deli’ which is more or less serving the same thing.
When the German diaspora increased in USA these shops began to adapt to their food restrictions (dietary practices unique to the Jews). In USA it became a combination of a restaurant and a grocery store. It offers a slightly variant menu from that of a fast food restaurant. In Europe it is more of a place which sells luxury and expensive food types.
As you can see culture intermingles with other cultures and brings a rich diversity and variation in to human experiences.
