slick vs sleek, Language Skills Abroad
Can both of them apply to cothes, hair and even things like a flat, a car or a garden?
I’ve been wondering what the difference between slick and sleek is! According to my dictionary, both of them mean “well-groomed”, whether it be fur or hair or somebody’s general appearance in a figurative sense.

Why should my definition of the slang word slick be omitted into a Standard English dictionary? That makes me think of a question that is even more basic. Why not? There are many words in the dictionary that are not as common and are better defined than slick is. Take for instance the word beater. When I looked it up in Webster�s dictionary, it had a slang definition that is well worded, and it was easy to understand why that word is used. It said that the slang word beater was an old car that is in bad condition. Although I have heard this word before, I think that beater is less popular and less used in normal conversation than the word slick. My definition of the slang word slick, a person who is clever, who could also be a cheat or a swindle, serves to show that this word is common and can easily be used in normal everyday conversation.
I think that the reason the slang definition of slick has stayed the same, and stayed common amongst all generations, is because the literal meaning, and the slang definition are so similar in use. The word fat in the example above is not shared by many generations because the literal meaning of fat and the slang definition of phat are so far apart that it is hard for people of different ages to accept the new meaning. It takes many years for people of all ages to realize that a word has changed and many more years for people to realize how to use it in its new application. The slang use of slick has withheld the test of time, and it will continue to stay the same for many years.
