Question

Fill in the blank with the most appropriate word.
_____ other day I had a letter from my friend.

• A. A
• B. An
• C. The
• D. No article

Answer 1

Answer: (C)

The

1. An/A' is used as an indefinite article for a thing or person when the reader doesn't know which one we are referring to out of many nouns. It states the random nature of the subject.
2. 'The' is used as a definite article for a thing or person when the reader knows which one we are exactly referring to. It states the specific nature of the subject.
   

Option C is correct as 'The' is used with words which have been mentioned previously. The readers are aware of that day. Option A is incorrect as 'A other day' sounds illogical and is grammatically incorrect. Option B is incorrect because 'An other day' implies any random day that the readers are unaware of. Option D is incorrect as an article is required in the blank to give meaning to the sentence.
