Learn English – Adverb placement: “There is still” vs. “there still is”

Yes - I can't find anything grammatically wrong, but certainly your second example doesn't sound natural. It's probably, as you imply, that a lot of information is being condensed into a small space, when it might be better put in extended constructions (get a move on with those prepositional phrases!) or even more than one sentence.

She waited outside this morning.

She waited impatiently outside.

??She waited impatiently this morning.

She waited impatiently outside the school this morning.

She waited - impatiently - outside, this morning.

She waited outside this morning. Impatiently.

Of course, there are some who would say that outside is an intransitive preposition in your second example (and in four of mine).

I've found an article covering 'the Royal Order of Adverbs' at the Farlex Grammar Book. Here are some salient points:

What is the order of adverbs?

Because adverbs are used to modify verbs, adjectives, other adverbs, phrases, clauses, or even entire sentences, they are able to function nearly anywhere in the sentence, depending on their type and what it is they are modifying.

If we use more than one adverb to describe a verb, though, there is a general order in which the different categories of adverbs should appear—this is known as the order of adverbs (sometimes called the royal order of adverbs):

1. Manner

2. Place

3. Frequency

4. Time

5. Purpose

Of course, it is uncommon to use five adverbs in a row to modify the same word, but if a sentence uses two or three, then it is best to follow this order to avoid sounding unnatural....

(*Note: For the sake of conciseness, both single-word adverbs and adverbial phrases will be referred to together as “adverbs” throughout this section.) ...

[I]if we were to make a sentence with all five categories of adverbs together, it might look like this:

“I have to run quickly (manner) down the street (place) each morning (frequency) after breakfast (time) in order to catch my bus to school (purpose).”

Even though the string of adverbs is unusually long, the sentence still sounds smooth and logical because the order is correct. Now let’s try rearranging the order of the adverbs:

“I have to run each morning (frequency) quickly (manner) after breakfast (time) in order to catch my bus to school (purpose) down the street (place).”

By changing the order of the adverbs, we’ve actually changed the meaning of the sentence, or at least made the original meaning nearly incomprehensible. This is especially apparent with the adverbial phrase of purpose 'in order to catch my bus to school'— by placing it before the adverb of place, it now sounds as though it’s the school that’s down the street. There is not such a drastic shift in meaning for the adverbs of frequency, manner, and time, but they still sound awkward and unnatural in the new order.

When we can change the order

There is a great deal of flexibility regarding where in a sentence an adverb can appear, regardless of its content and the rules of order that we looked at above. While the order of adverbs is useful to keep in mind, it is a guide, rather than a law.

Multiple adverbs of the same category

When we use multiple adverbs of the same category to modify the same verb, we order them based on how specific the information is that they provide. For example:

“On my father’s ranch (place), I often (frequency) helped gather the animals at the end of the day (specific time) when I was younger (non-specific time).”

“I lived at home (more specific place) with my parents (less specific place) to save money (purpose) while I was working on my doctorate (time).”

And if the Royal Order ruling has to be seen as a rule of thumb, it is almost inconceivable that this codicil is more binding.

After checking out a number of sites on the Net, it seems that most of the grammar pages say that adverbs of manner, like nicely, normally come after the verb. That may be true.

I find that it all depends on what I want to emphasize in the sentence. In the biomedical papers that I edit, I always change "as described previously" to "as previously described". Why? It sounds better to my ear because I put primary stress on the first syllable of previously when it comes before the verb, and seems to me to be the proper word order for what I consider a set phrase that should emphasize previously rather than described.

Most adverbs of manner can be placed before or after the verb. As Chris says in a comment, it slightly changes the emphasis and the rhythm of the sentence, not the meaning.

Whoever told you that the word order was incorrect was wrong. It's not incorrect; it's merely a personal preference, a matter of style, not grammar and not semantics.

I look at you all
See the love there that's sleeping
While my guitar gently weeps

The rhythm of the sentence is what's important in these lyrics. It's perhaps less important in a science paper, but I usually[1] think about it when I edit.

Putting an adverb in the wrong place can change the meaning and focus of the sentence. I tend to ignore "rules" about adverb placement when I write and edit. I think about where each word belongs in each sentence in context, not in theory.

NOTE [1]: "...but I think usually about it" changes the meaning of the sentence.
