Unfortunatly or Unfortunately?
Unfortunately
Exemple : ‘’Unfortunately I am going to have to decline your invitation as I have plans.’’
The letter "e" in the word "unfortunately" is often missed out due to the fact it is not clearly enunciated. The word is comprised of the prefix "un" along with the adjective "fortunate" and the suffix "ly." It is from the word "fortunate" that the letter "e" is retained.
