Well, more often than not, you will notice funny spellings on shops, carts and other selling points. More often than not, these spellings are in English or the words are taken from English language and written in Hindi or any other regional language. But it is so shocking to see Hindi words written wrongly in Delhi.
The above picture shows a shop selling all the materials related to Navaratri festival.
This photo is taken in Kamla Nagar, Delhi. Please excuse the quality of the picture as I was driving when I took the picture.
The proper spelling should be व्रत and not वत्र. This happens when you put the त as half instead of half व.
