Example Input: I understand the capitalization rule for nouns, proper nouns require a capital letter. Also, I should begin a new sentence with a capital letter. When & why 'mom/dad' requires a capital letter ? (Reference- ELL- I am at Vapi where mom is hospitalised) mom: (n) informal term for a mother/North American term for mum.
Example Output: When it is their name, Mom and Dad would be capitalised: Dear Mom and Dad, I am just writing to let you know, that although everyone has a mom and a >dad, you are my special mom and dad. So, Mom, I just want to say 'brava!'; and Dad, 'bravo!'. I've just been telling Sis, that Mom's new coat is so cool. XX Here's the commentary from an exercise from BBC English on Line ...to have a roast chicken lunch with my mother. I can't wait! - mother does not need a capital 'M' as it is not being used to replace her name. If I said, 'I am going to lunch with Mum', it would need a capital letter, but 'I am going to lunch with my mum' does not.

Example Input: What is the difference between 'day off' and 'off day'? What I found is 'day off' means a holiday when you are not working, while 'off day' is the day when you do not work up to the mark. Can anyone put more light on this?.
Example Output: you are correct, the word 'off' like many small english words has a large number of meanings, some of them are even opposites. 'day off' meaning 'not present this day' Either scheduled break or due to dishonesty, illness or other emergency. off(adverb) 'away from a place' 'off day' meaning 'not performing well this day' off(adjective) 'not up to standard; not so good or satisfactory as usual; inferior or subnormal'

Example Input: Possible Duplicate: How do I say 'Our meeting is preponed'? A friend of mine asked me this question, and it caught my curiosity. Is there an explicit opposite of the word postpone? As in, do something in advance? Clearly what I just said is functionally equivalent to the answer I am seeking, but I was wondering if there was a single word that is the antonym. More context: Bob was supposed to start work in July, but due to a work visa issue, he had to begin in advance.
Example Output:
The most business-speaky option is expedite. Other alternatives include accelerate, hasten, and advance. Technically prepone is in fact the precise antonym, but I honestly wouldn't be caught dead using it.
