So I had to check my friend"s homeoccupational, yet I myself do not also recognize the answers. For instance:

"Yes, they are. They are both tall and they have actually both got brvery own eyes.

You are watching: They both are or they are both

"Yes, they are. They are both tall and also they both have gained brown eyes.

I am leaning towards "they have actually both got" (#1), but I cannot rationalize why, or why the other option would be bad.

Which is correct, and why?

Edit: Her teacher wasn"t precisely of much help as soon as she shelp that it is just the means it is. The answers are displayed below.

A copy of her homeoccupational is below:

There are six (6) pairs of options in her homework: that is, six (6) inquiries. So that gives a total of twelve (12) choices. Of those twelve (12) choices, all other than for 2 (2) are grammatical.

It so happens that 4 inquiries have actually no wrong answer, and also just two inquiries have actually a right/wrong pair as answers. (Aside: I like that kind of homework!)

CAVEAT: Several of the grammar info that I"m presenting in this write-up might be intentionally--or unintentionally--over streamlined. Hopetotally there won"t be any type of egregious errors. (I"m sure I"ll obtain dinged if tright here are.)

Let"s initially execute a little grammar review, and then later we"ll look at her homework-related.

There are two primary offers for the word "both":

One: a marker of coordination -- This is typically taught in a formal leschild. The word "both" is used to mark the initially coordinate of an and-coordicountry of 2 coordinates. E.g. "He likes both apples and pears", "He likes to both run track and also swim relays". This form of use is rather straightforward, and it is an easy topic taught in schools.

Two: a quantificational adjunct -- This can only be lightly taught in a formal lesson, or maybe perhaps not taught at all. The word "both" is functioning as an adjunct, which is a modifier that is optional for a given sentence. It can be omitted via no loss, or practically no loss, in meaning (usually). It behaves in a similar fashion as conventional grammar"s "adverbials" (which are also adjuncts), e.g. "They would both/quickly run to college in the mornings".

It is typically possible for a speaker to place a quantificational adjunct right after the subject. (e.g. "We both can sing tonight".)

When a clause is headed by an auxiliary verb, then a speaker have the right to typically place an adjunct ideal after that verb; and also often tright here could be a preference to have actually the adjunct situated after an auxiliary. (e.g. "They would certainly both/quickly run to institution in the mornings".)

When a clausage is headed by a transitive lexical verb, then there will certainly regularly be some resistance to having an adjunct situated in between the verb and its object. (e.g. * "They play both the guitar", which is ungrammatical.)

Auxiliary verb: An auxiliary verb deserve to normally be identified by verifying that it can take part in subject-auxiliary (verb) inversion. For example:

"They are tall" has the subject-aux invariation of "Are they tall?"

"They can run fast" has actually the subject-aux invariation of "Can they run fast?"

For those over examples, the auxiliary verbs are "are" and "can". The auxiliary verbs switched spots with the subjects as soon as they underwent invariation.

Sometimes it can be unclear regarding whether the word "both" is functioning as a quantificational adjunct or as a marker of coordicountry. Consider this possible ambiguous example:

"We have the right to both sing and also dance."

The 2 various interpretations can be seen once it is compared against:

"She can both sing and also dance." --

"We deserve to both sing." --

Now let"s evaluate the instance choices by question.

Inquiry #1:

1.a They are both tall.1.b They both are tall.

The above 2 examples are grammatical bereason the word "both" is functioning as quantificational adjunct in both.

That is: in #1.a, the word "both" is after the auxiliary verb "are", and also in #1.b, the word "both" is after the subject. And both places are valid slots for the quantificational adjunct "both".

Question #2:

2.a They have actually both acquired brvery own eyes.2.b They both have acquired brown eyes.

The above two examples are grammatical because the word "both" is functioning as quantificational adjunct in both.

That is: ditto as offered for question #1 over, except that the auxiliary verb here is the verb "have".

Question #3:

3.a They both like rock music.3.b They favor both rock music.

Example #3.a is grammatical bereason the word "both" is functioning as a quantificational adjunct. The reason is the very same as offered for example #1.b above: that is, the word "both" is after the subject.

Example #3.b is ungrammatical. The factor it is poor is because the word "both" is functioning as a quantificational adjunct, but it is situated after a transitive lexical verb ("like") and prior to its object.

Inquiry #4:

4.a They play both the guitar. 4.b They both play the guitar.

Example #4.a is ungrammatical. The reason it is bad is because the word "both" is functioning as a quantificational adjunct, but it is situated after a transitive lexical verb ("play") and before its object.

Example #4.b is grammatical bereason the word "both" is functioning as a quantificational adjunct. The factor is the very same as given for example #1.b above: that is, the word "both" is after the topic.

Concern #5:

5.a They both are great at tennis.5.b They are both excsteustatiushistory.orgent at tennis.

The above 2 examples are grammatical because the word "both" is functioning as quantificational adjunct in both.

That is: ditto as offered for question #1 over.

Concern #6:

6.a They are both lively and confident.6.b They both are lively and also confident.

The over 2 examples are grammatical, yet the initially of the pair is ambiguous regarding just how it might be interpreted.

Example #6.a is grammatical because of among the following reasons:

Words "both" might thought about to be functioning as a quantificational adjunct that is situated after the auxiliary verb "are". Which is the exact same factor as given for example #1.a above.

Or the word "both" could be thought about to be a marker of coordicountry, wbelow the 2 collaborates are "lively" and "confident".

Example #6.b is grammatical bereason the word "both" is functioning as a quantificational adjunct. The reason is the same as provided for example #1.b above: that is, the word "both" is after the subject.

EXTRA INFO: Some associated grammar excerpts

The 2002 CGEL, web page 1305:

2.3 Both and either

The determinatives both and also either function in the framework of NPs or of coordinations:

<38>

i.a. both players - - - - b. both Kim and also Pat

ii.a. either player - - - - b. either Kim or Pat

In the NPs they attribute as determiner, as described in Ch. 5, &&7.3, 7.7. In the coordicountries they function as marker of the initially coordinate in correlative coordination: both is paired with and, while either is paired via or. (fn 25)

The 2002 CGEL, web page 102:

A similar distinction in place in between auxiliaries and lexical verbs is uncovered via specific determinatives, such as all, both, each (…), that are semantically associated with the subject:

<36> - - - - - LEXICAL VERB - - - - - - - - - - - - - - - AUXILIARY VERB

i.a. All the players took a card. - - - - - - - b. All the players had taken a card.

ii.a. The players all took a card. - - - - - - b. The players all had taken a card.

iii.a. * The players took all a card. (*) - - - b. The players had actually all taken a card.

In the versions all belongs syntactically and also semantically in the subject: it functions within the NP all the players and also it quantifies over players. Such items deserve to be positioned exterior the NP, and the versions display all in pre-verbal place. If the verb is an auxiliary, it can follow the verb, as in . But it cannot follow a lexical verb, as is evident from the ungrammaticality of .

The 2002 CGEL, page 413:

One usage of fused-head partitives that merits separate mention right here is that where they function as quantificational adjunct in clause structure:

<13>

i. Her parents both felt she had been exploited.

ii. They had actually namong them intended to reason so much ill will certainly.

The quantificational adjuncts serve to quantify the subject. Example is therefore indistinguishable to Both her parents felt she had actually been exploited and also to Namong them had intended to cause so much ill will. Universal all, both, and also each have the right to occur as implicit partitives, while the collection of determinatives uncovered in explicit partitives is substantially larger: these three together with existential some, any, none, cardinal numerals, multal many and much, paucal few, a few, and also several.

The implicit partitives have the right to take place in preverbal place, as in ; explicit partitives are somewhat questionable in this position, strongly preferring post-auxiliary place. Compare ?Her parental fees both of them felt she had been exploited and also Her paleas had both of them felt she had actually been exploited.

The 2002 CGEL, web page 428:

<7>

i.a. We all/both took pleasure in it. - - - - - - - - - - b. We had all/both appreciated it.

ii.a. You each qualify for a prize. - - - - - - - b. You will each qualify for a prize.

iii.a. They all five of them complained. - - - b. They are all five of them complaining.

In this building the underlined expressions (italicized bold expressions, F.E.) are quantificational adjuncts functioning in clausage framework. This is apparent from the fact that as soon as the verb is an auxiliary they preferentially follow quite than precede it, as in the examples.

Some connected examples from the 1998 SPE. An instance is grammatical if it is unmarked (most of the examples below are grammatical).

Page 98, #2:

Tom"s hands both were filthy.

Page 170, #10:

The youngsters all need to have fallen asleep.

The youngsters need to all have actually fallen asleep.

The youngsters have to have actually all fallen asleep.

Page 244, #5:

The employees all might have actually been drinking coffee.The employees might all have actually been drinking coffee.The employees might have all been drinking coffee.% The employees might have been all drinking coffee. (acceptability varies dialectally)

Page 245, #6:

His hands were both filthy.

Page 521, #2:

The guests both drank beer.* The guests drank both beer. (ungrammatical)

I did a quick look at the teacher"s answers. Tright here are a variety of grammar worries in play: such as, transitive verbs (e.g. "play") have a resistance to having actually some kinds of adjunct (e.g. "both") in between the verb and its object. Also complicating the concern is that the word "both" can be a marker of coordination, e.g. "She plays both the guitar and piano".
