Yes, it should be hyphenated like so: sixteen-year-old boys.
No, but you may do so if it seems better.
Correctly it should be, but the meaning is clear without it, so many overlook it
No, it is not hyphenated. In this colloquial phase, the word "location" is used as a specific place. In being so, "on" is a separate preposition that is not to be hyphenated.
you took the risk of falling an should have talked about it before so now you have a choice either you tell him about the baby or take off an forever not see him again You had your fun now you have to face the task master so to say
So much fun!! If you aren't playing it, you should!
"Custom tailored" is hyphenated when it precedes whatever it modifies, so you would hyphenate it in forms like "a custom-tailored suit". However, if it is a predicate adjective, it is not hyphenated, so you would say, "All his suits are custom tailored."
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.
Well, I just did an experiment on that, and with an ordinary lecture, the average grade was a 50. In a fun class, the average score was 63. So yea, learning should be fun!
No. Whatsoever is actually a real word.
just go somewhere where you think is a fun place..
daydream is one compound word, so you do not need a hyphen.
