Cambridge Dictionary adds one of the most used Urdu words to its list

Accha! Cambridge Dictionary has made an addition to its list of words with a word of Urdu origin which has amused the Urdu readers.
Nevertheless, many Urdu users have expressed reservation over its spelling which they suggest should have been acha with single c rather than accha. Another thing that irritated people is that the word is being associated with India, while Urdu is Pakistan’s national language, albeit it is widely spoken in India as well.
Interestingly, Oxford and other dictionaries use a different spelling for the same word which is achcha, however this too does not fit the spelling adopted by its original users.

Its meaning has been described by Cambridge Dictionary as “(it’s) used for showing that you agree with something or understand something.”
This is also fascinating that the dictionaries realize that the word can be used for different meanings in different situations. For instance “to express an emotion such as surprise, doubt, joy, etc.” This thing was specially described by PK in the movie with the same name in detail.
