It's fall, y'all! And while you may be making jam and apple sauce right now, let me entertain you with some fruity idioms, as fruit is very commonly used in the English language, it seems. Want proof? How about: "An apple a day keeps the doctor away" – a good reminder to eat your 5-a-day. When someone behaves slightly crazy or silly you would say they "go bananas". And let’s not forget the expression "cherry-picking" to describe the act of choosing the best from a list or group.
In German, we also use fruits to express ourselves in a more colourful and interesting way. But while the British compare apples and oranges, i.e. apparent differences between incomparable items, we will compare apples and pears! To us, the latter are obviously more dissimilar than the former two.
