Ah, I presume you mean you looked up thank-you, which is an existing noun but not the same thing at all as the common idiom thank you.
Merriam-Webster tells us:
Full Definition of THANK-YOU
: a polite expression of one's gratitude
Origin of THANK-YOU
from the phrase thank you used in expressing gratitude
First Known Use: 1792
Now, the phrase “thank you” ...
I don't think you're going to be corrected or admonished for using any of these three. Google understands you perfectly no matter how you type it. Wikipedia features all three as well.
Personally, I'd write it as 'backend' or 'back end' as I'm not a fan of over-hyphenating (excuse my hypocrisy) unnecessarily.
The NGram essentially supports ...
You should not use hyphens in these instances.
We do not hyphenate such noun phrases when they are used in ordinary nominal contexts such as object of a preposition or argument (subject, object, complement) of a verb:
He has been a realtor for thirteen years.
Thirteen years have passed since he entered the real estate business.
He has spent thirteen ...
You have four examples due to how the words are being used differently in each case.
The noun phrase “brute force” describes the raw strength used to achieve or get through something. For example: "Greg used brute force to open the stuck door."
Below is an explanation of the different formats you found. I have also linked to an article about hyphens and ...
Spell it as back end when used as a noun, as for example "I am working on the back end of a project", and
Spell it as back-end when used as an adjective, as for example "The back-end technologies for this project will be Apache, MySQL and PHP."
Hyphenating compound adjectives is common in English, and both the links above use the hyphenated form ...
Quick answer for general use:
hyphenation is for adjectives, not adverbs:
They sheltered in place. [no hyphen]
The dancers twirl in place. [no hyphen]
The in-place sheltering command was given at dawn. [adjective]
The boilers were replaced on site.
On-site replacement of boilers is offered by the company. [adjective]
Yes, the hyphen should follow 10. In addition, a space should follow this hyphen, indicating that 10- is attached to year-..., not to to:
...the time spent by 10- to 15-year-olds on two activities
Note that spent, the past participle of spend, is employed as an attributive.
This is not a question of grammar, but of style. Writers use hyphens with compound adjectives to avoid ambiguity so that the reader does not have to read and re-read a sentence to garner the meaning from it.
John was a white bearded man.
Someone might try to parse this sentence at first to mean he was a white man who had a beard.
John was ...
Firstly: neither phrase needs a hyphen. The use of hyphens can be tricky, but here the relevant rule is that they are used to make compound modifiers. Use a hyphen to link a modifier to another word, when the two together then modify something else.
He is well liked. ("Well" modifies "like".)
He is a well-liked person. ("Well" modifies "like", ...
"How many days was the tour" is the only option there that is correct.
I'd still definitely prefer to use "how long was the tour".
Edit: as Jack said, option 2 "How many days of tour were you on" sounds possible, but it is quite awkward and I would probably never say it. Options 1 and 4 are wrong.
Edit: as alephzero said, option ...
Robusto's answer is correct, I'm just adding another thought.
Is this a case of people making a grammatical mistake or are both forms completely correct and it's just a matter of preference?
Robusto didn't quite address that question head on. While there is a lot of flexibility in punctuation, I would say any professional editor worth his or ...
When a measurement is used right before the noun it measures, use a hyphen and the singular form of the unit of measurement:
I saw a 95-foot yacht in the harbor.
The 12-mile climb is too arduous for casual visitors.
The monument is in the 13.7-acre park's circular drive.
A dimension can also be included with another hyphen:
I saw a 95-foot-long ...
I think the word you're looking for is long-term. We refer to long-term benefits or long-term goals. Long run would make more sense like this:
I know it seems difficult now, but these changes will make things better in the long run.
Long-term is hyphenated because it's a compound adjective. The long run is not; I'm pretty sure it's a noun phrase.
Thank you contains a verb(thank) linked to an object(you). This is how we normally thank people.
For ex: "[I/we] thank you for being here."
Like many other phrases, this commonly used phrase was turned into a single hyphenated word, 'thank-you'. It is considered as the noun/adjective form of 'thank you'.
For ex: I sent him a thank-you card.
"Typed" here is an adjective. As I think your intent is that "arbitrary" is modifying "typed" and not "data", that is, the data is not arbitrary, but rather the typing of the data is arbitrary, you need an adverb. So you should say "arbitrarily typed data".
No hyphen is needed. You don't use a hyphen when using a conventional adverb-adjective-noun sequence....
From the Microsoft Style Guide:
back end, back-end
Don't use if you can substitute a more specific term, such as server,
operating system, database, or network.
Two words as a noun. Hyphenate as an adjective.
According to the Chicago Manual of Style you are right and it should be "Forty-five-year-old [man]". Quoting from the Chicago Manual of Style (14th edition, page 223):
six year-old girls
man sixty-five years old
child two and a half years old
In the "getting-to-know-you stuff", the hyphenated part is a 'modifying phrase'. It basically fulfills the role of an adjective. Outwardly it reminds a 'compound adjective', but does not have the typical characteristics of an adjective.
The key thing that makes it work like an adjective here is that it is in the attributive position relative to the noun "...
The general rule for noun phrases like this is to separate them by spaces.
However, many* specific pairs of words have exceptions and are either written hyphenated, or are even merged into a new word with no separation at all. For example, "copy editor" is in the process of moving from unhyphenated noun phrase through hyphenated noun phrase to new word, ...
Two words are joined by a hyphen when the collocation occurs in a non-standard context. For instance, we speak of the front end (space, no hyphen) of a car when this acts a noun phrase:
The front end of my Chrysler was dented.
My Chrysler was hit on the front end.
But when we use front end as an attributive, we hyphenate it:
My Chrysler suffered a ...
A Samsung-sized marketing budget
Since Samsung is a multinational corporate giant, I would expect this to refer to a very large budget.
airport-sized publicity stunts
An airport is a very large facility. So I would expect this phrase to mean roughly:
A very large budget buys you a giant/huge marketing campaign (which would include big publicity ...
When we use counted elements as adjectives, they take a hyphen and lose the plural ending -s, because adjectives don't have plural forms in English:
Here are some examples:
a two-year program,
a 3-day hike,
a two-hour test,
a four-year-old child,
a 100-year war
"In-depth" is an adjective which means comprehensive and precise, while "in depth" is a phrase or idiom which works like an adverb, meaning the same, so as comprehensively and precisely. Examples:
An in-depth analysis of the problem.
The problem was analysed in depth.
Hyphens are used in English in a number of distinct ways. Here are a few:
They are used to form compound nouns. For example "the be-all and end-all" or "back-formation". Most often compound nouns are just written as one word with no hyphen. It's best to check a dictionary to see which form is preferred.
They are used to join a prefix to a proper noun. For ...
What we are looking at here, is a simple pair of adjective + noun.
Grammatically speaking the same pattern as:
Therefore: No, there is no hyphen. Your phrase remains as:
"Temperature is low" is the first rule's premise.
Even native speakers might be confused which to use, so the answer is really "both can be correct". "End user" is such a relatively recent term that there is no "standard" way to write it. However as Mick points out in his comment, it can be clearer to hyphenate compounds like this when using them as adjectives.
However, none of your examples make much ...
I believe this is a style issue rather than a question of grammar. That is, different publishers may have different preferences for when to use a hyphen.
In the style I learned (for academic technical writing), a hyphen is used when combining words to make an attributive. For example, "a fifteen-foot boat" or "a two-year assignment". A hyphen is not used ...
