I was wondering what the word Lan means when put on the end of a sentance. My friends always say it and when I asked them to explain they couldnt.... Or is that they didnt want too    

My dictionary says it means ´hey,you´   ´say,man´  ´listen,buster´  but a Turkish speaker will probably help.

According to www.tureng.com lan is something like man, mate. I think it´s the same as ulan, which according to the dictionary is something like "bud, buddy, twerp".

These are just dictionary definitions, I´m sure the natives can elaborate on the colloquial use better.

 It´s generally a word used between men/boys - you can look it up on the dictionary on this site

here - ´lan´ directs you to ´ulan´  It´s not particularly polite but then again I don´t think it´s that rude - I hear it used a lot.

Thanks, someone did say to me that this may be the case but then when my boyfriend and me were messing about he told me to souslan (excuse me if I have spelt that wrong) a female friend at the table said that he was telling me to shut up b@tch and I was concerned that he had been saying this to me infront of people, he however said that this was not the case! 

dont worry maureen hes not calling you a bitch, I say this all the time to my close turkish friends, maybe its not that ladylike but im not that ladylikehes just joking with you.and its SUS LAN, like, be quiet you

Yeah, that is what he said!

I think that she was trying to make trouble because he got quite annoyed with her.

And althought we bicker and he can seem a bit off sometimes he is never blatently rude to me. I did think that it was a bit strong! thanks for clearing that up for me.   

It may be a dangerous word when one use it for someone who he doesn´t know. I remember I wrote something about this topic in this forum, but I can´t find it easily right now. But I will try to say a short story of the word.

"lan" is not a normal word indeed. It comes from "oðlan". It becomes "ulan" sometimes. But ulan and lan are not used for normal conversations. Ulan might be bit more dangerous than lan. If you are talking to someone who you know closely, as a "buddy", someone like bestfriend (and generally it is used between guys), this might be a mischief conversation. Or you might be between friends, and no one gets the words offensive, then it can be acceptable or normal or ok. But it is a vulgar approach, so you shouldn´t use it for those who you don´t know much or who you must show some respect.

Other usage is; if someone is angry, then he may use this word against to with whom he angry is. That is not a friendly approach. That is the vulgar one.

I remember I was about to be fighted when I was a kid, since I called a guy "lan" as a habit of the childhood, not as anger. Then I realized it is a dangerous word.

i know for lan different in english word turkish lan mean in english lad if i´m not made a mistake

 I don´t think so because ´lad´ is always used in an affectionate, friendly way as far as I know.
