To address
In spoken Malayalam, there are some informal words to address someone. This can be used to call some one rudely,with anger or between very close friends to address in formally. It is very common between close friends.
edaa, da, daa : calling a male friend.
edii, di, dii : calling a female friend.
When you are disturbed by someone you may tell him/her "go away"
Lets start with the word go = pookuka.
poo= go ( asking to go informally)
poodaa = go ( asking to go bit rudely to a male)
poodii = go ( rudely to a female )
But the above words are not cursing words between close friends. These words are common just to tease/ make fun etc. But it can be cursing depending upon the way you say it or shout. Especially when you address a stranger like this, it will be bit insulting or rude. So be careful. You never call edaa/edii to an elder person. Between couples, wife normally does not address husband like this.
As shown above, da or di can be combined with other verbs to address informally. Like,
vaadaa ivide = come here ( varuka = to come; ivide = here )
thaadaa athu = give that ( tharuka = to give; athu = that )
Calling someone...
When you call some one with his/her name, it is common to modify the end of the name to get the feel of calling. For example:
Dileepee : you are calling Dileep. ( may he is sitting in the next room)
Nishaaa : you are calling Nisha
Note that, if the name ends in a consonant, -ee is added. Or -aa is added. But the converse can also be true.
Telephone...
To telephone someone, you can use the word, phone vilikkuka = to phone ( vilikkuka = to call ). When someone calls you, take the receiver and you may say "Hello"
Let us wish...
It is very common to say "hi" or "hello" when you meet a person. Even though these terms are English, they are well accepted. Also, good morning, good afternoon, goodnight are widely used and their Malayalam alternatives are mostly not used in spoken language. They are too literal. It is not at all common to say 'hi' to a stranger.
To thank someone, it is common to use 'thanks/ thank you". In response, you may use "you welcome / no problem". The English word 'thank you/thanks' is widely used in Malayalam. But the in Malayalam,
nann'i = thank you ( bit formal )
valare nann'i = thank you very much
kuzhappam illa = no problem ( not very common )
kuzhappam = problem; illa= no
Also not that many people, even though they are thankful, they wont express it with words for every silly things.
