Yes, I practice calligraphy. Aah... I can hear you whispering, "What the hell is it?"

Well... According to Oxford Dictionary, the word 'Calligraphy' is a noun and it is defined as...

  1. Decorative handwriting or handwritten lettering.
    ‘a label written in admirable calligraphy’
  2.  The art of producing decorative handwriting or lettering with a pen or brush. 'you could watch professionals demonstrating lettering and calligraphy’

If we talk about the origin of this word, once again, I am here explaining with the help of Oxford Dictionary, "Early 17th century: from Greek kalligraphia, from kalligraphos ‘person who writes beautifully’, from kallos ‘beauty’ + graphein ‘write’."
I hope, you know it now. One thing more, when you tell your friend about it, remember, it is pronounced as /kəˈlɪɡrəfi/

I can once again hear you whispering... say, say, what do you want to know?
Oo... Callikaari / Calliکاری / Calliकारी
Well, my friend, there is a short story behind it...
