Sort Of, Kind Of
I was trying to explain the difference between “sort of” and “kind of”. This was very difficult to do. The phrases are nearly identical. However, they are not entirely identical; we would not use both of them if they were.
The best I could come up with is the following: “sort of” implies a brotherly (or sibling) relationship; “kind of” implies a parental (or hierarchical) relationship. So when comparing a pear and apple, we would say, “an Asian pear is sort of an apple”. When talking about Tomatoes we say, “tomatoes are kind of a fruit”. All apples and pears are fruit, but not all fruit are apples or pears. A fruit is either an apple a pear, or some other fruit. Likewise, tomatoes are neither apples, pears or (classically speaking) fruit. They might be both tomatoes and fruit, but they are definitely not both apples and tomatoes.
So a tomato is kind of a fruit but sort of an apple.
What is interesting is how we would use this. If I am explaining shogi to an American, whether I say it is sort of like chess or kind of like chess hints at how I think about the game. Using sort of implies that it is more distinct; kind of implies more that it is a derivative of chess.
So with this all being said, Spaghetti is kind of like Ramen. Mochi is sort of like Mozzarella cheese. And Lasagna is just amazing.
