PROBLEM: Question: 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. 
Answer: We should capitalize these words if they are being used as the name of the person. You can capitalize these when referring to your own relatives: Hello, Mother. When you use mom/dad in general meaning father/mother, it's a common noun. So do not capitalize them when they follow possessive pronouns such as her, his, my, our, your. (my mother ~ my mom ) A good rule to follow is to capitalize them if they are used as proper nouns. (dictionary.com).

SOLUTION: no

PROBLEM: Question: I just noticed that the word in the movie title The Pursuit of Happyness is spelled with a y instead of an i. But my spell checker highlights "happyness" as a mistake. Why is it spelled differently here? Shouldn't it be happiness? 
Answer: It is happiness, in the same way it is luckiness. Happyness is a typo, whatever it is intentional (e.g., to make fun of somebody who wrote that word) or not.

SOLUTION: no
