There's a few reasons oil would be in a cup.
1) Oil is served for dipping bread. Though usually in a bowl, a glass can be used.
2) A little olive oil can do wonders for a salad. It is easy to drizzle on from a small glass.
3) A cup of oil with a wick makes an excellent candle. The soft light is beautiful.
4) When cooking and out of oil, a friendly neighbor is likely to give some in a glass.
Hello! Just an Australian perspective. We do not put oil in a glass or a cup. They are for beverages and tea/coffee. We put dipping oil in a small dish, often next to two other dishes, one with balsamic vinegar and the other with dukkah. Your second point: Yes, we drizzle olive oil on a salad, but it is called a bottle or small jug, not a glass. Yes we use oil in a container with a wick for burning, but this is not called a cup, we just call it a container. Lastly, a friendly neighbour would not use a glass for cooking oil, but a bottle or perhaps a small jar. In recipes, if oil is to be added to whatever you are making, it is often referred to as a cup of oil, but this would be a purpose made measuring cup, not a kitchen cup. Greetings from Australia and happy language learning!
My French teacher would disagree. Knowing how to spell words helps to differentiate between words that are spelt similarly but mean different things. Plus it slows you down and makes you think, increasing the likelihood you will remember information. It's one of many methods of teaching.
Hi kjb, both bicchiere and beaker have origin from the Latin BACAR wine vase (bàcara= little stein, mug). It seems shaped by Latin bàca (Italian bacca) berry, from this one the sense of a rounded thing, of vase. Then bacar becomed bàcarium>bìcarium. In the Old German bacar get in behha, behhari, German becher, Englis beaker.
