Question: I often say something like:

> 
> This soup is pretty damn spicy!
> 
> 
> 

I am wondering now if this is actually proper grammar.

On [Urban Dictionary](https://www.urbandictionary.com/define.php?term=pretty%20damn), it says the meaning of it is *“approximately”*, but when I use this term I don’t use it for “approximately”. Like the above example, I used it for saying “pretty spicy” or something like “actually pretty spicy”. I hope you get the way I use that term.

But still, I am wondering if that is proper or not.

I am also wondering if this is maybe too dirty language, so you can also say whether I should often say this or not.

Answer: 
*Damn* works as an intensifier, similar to *very*. *Pretty* is much milder, and has a sense of "more than expected", "more than average". It actually works to soften *damn* in this sense, giving it a sense of "this is surprising!"

It's definitely informal language, and some people would be offended by the word *damn* anyway, but it's extremely common to hear, so I wouldn't call it "dirty language" really. It depends on the company you use it in!

A common thing nowadays is for people to soften their language intentionally, partly for fun and partly because it feels nicer and friendlier - not out of a sense of decorum. So consider using "this is pretty dang spicy!"
What is "proper" is really opinion-based. Some people find "damn" offensive, while many do not.

What I can say is that it is not polite and would not be used in a formal setting. You might say it to people you know well, but probably wouldn't say it at a job interview.

Again, what is "dirty" is opinion-based. Many people divide curse words, or swear words, into the categories of just plain offensive (for example, scatological terms), and sexual (for example, the 'F' word, or slang terms for genitalia). It is the latter that people normally think of as 'dirty' language. 'Damn' originally had religious connotations - it means to condemn to hell - so it doesn't have any sexual connotations. If people do find it offensive it is likely because of the original religious meaning, although these days, it is just used as an *intensifier*, as it is in your example.
