sick vs ill

From my experience, in the USA people use ‘buddy’ or ‘bud’ as slang words for ‘friend’.
Also, to address a male, they say ‘dude’ (as opposed to ‘block’ in the UK).

I initially thought that ‘mate’ was intrinsic to Australia.

We have a myriad of terms for “friend” in the United States. I’m not sure “buddy” tops the list for frequency.

I’m sorry but here in the UK it is common to use “mate”, it means your friend or “dude”, If I used dude, people would stare at me wierdly, although dude is also popular to use among a few youngsters.

What about ‘homie’ or ‘homeboy’ or ‘pal
Are those popular in the UK?

TIE, “dude” doesn’t mean “friend” in the United States. It’s just a very informal way to refer to males in general.

Dudes are less sensitive than girls.
Dude, what are you watching?
I don’t like that dude.

Note that the third would be especially nonsensical if “dude” meant friend.

pls understant that, I’m a foreigner in an English speaking country, I have to pick up the dialect where I live, and I have to ingore the american expressions. I have so many problems, when I use american expressions, even If I pronounce the word in american english. Jamie I think you should written " mate is not common to use in US english, it doesn’t refer to a friend in US english, but you generalized this word, which was a mistake, I think.

Mordant I know dude is a direct translation to mate, I know it doesn’t mean friend. In the third example it rather means fellow or bloke

I know all of these, but I never hear british people using it. Pal is in the usage as penpal, and I hear some people using it. Some old fellows told me, “But” is really widely used in some certain areas of Britain. Homie is too urban, I think. However Bruv or Buddy is commonly used. But definitely the most popular is “mate”.

Nowadays “dude” is getting more popular especially among youths

hi if the problem is serious he is ill if not he is sick.

i have heard it in movies .i think it is not wrong to use it.

Shekoofeh, the distinction you draw doesn’t hold. If my stomach hurts, I can say I feel ill. It can last three days, and we can call it a stomach illness.

What are you saying you have heard in movies?

i meant ‘dude’.was i wrong?i say it is true.

Dude is informal. It is fit for that use. It certainly isn’t fit for standard use.
