No, in most cases only the first word in a hyphenated word should be capitalized. Exceptions may occur depending on the specific style guide being followed.
Yes it should be hyphenated.
The general rule-of-thumb in contemporary English is that the first letter of the second word of a hyphenated term is capitalized in a heading only when it is a proper noun. Stricter style-systems (of which there are many) offer a variety of more precise rules governing these cases.
Any two or three word adjective should be hyphenated ONLY when used as an adjective. Example, "It was his thirty-second birthday." "There was a thirty second delay in rebroadcasting Carl's speech."
Only when it's being used as an adjective. If one says "These requests will be evaluated on a case-by-case basis," there should be hyphenation. However, if the phrase is used as a noun or an adverb, it will not have hyphenation, like so: "We will review these requests case by case." Basically, if it's modifying, or affecting the meaning of, a noun, it should be hyphenated. If it's affecting a verb (in the second case, HOW reviewing is done), then it need not be hyphenated.
No. In the word "zoology," the second syllable is typically accented, not the capitalized one.
Yes, the capitalized syllable in "DON-key" should be accented. The pronunciation emphasizes the first syllable, with a secondary stress on the second syllable.
The "Executive" is only capitalized when referring directly to the highest official in a government or institution. The phrase "executive session" is not. Conversely, the "Executive Officer" (XO) in a military hierarchy is usually second-in-command to the "Commanding Officer" (CO).
The first one is correct, the second one, the 'y' should be capitalized.
Just "Later" should be capitalized because it's at the beginning of the sentence. Grandparents doesn't neet to be capitalized because it's not specific and you are not naming your grandparents grandparents, like the difference between: "We visited my grandma today." or "We visited Grandma today." You are naming her Grandma in the second sentence so it needs to be capitalized.
No, because usually the song has it's own name which doesn't contain the words "national anthem". For example, 'The children sang the American national anthem, "The Star-Spangled Banner", so beautifully at this wonderful international event.' However, '"National Anthem" is a song recorded by American singer-songwriter Lana Del Rey for her second studio album, Born to Die (2012).' - from Wikipedia
