[Maybo]

Does the following sentence mean "the support" also lent her demeanour credibility?

The support lent her credibility, as did her demeanour. (Theranos scandal: Who is Elizabeth Holmes and why is she on trial? by Daniel Thomas)

 

[5jj]

The second clause does.

What do the meanings change when I say "The support lent her credibility, so did her demeanour"?

That's a run-on sentence. Otherwise the meanings are the same. The comma before "so" should be a period. Or you could use "and" before "so."

The support lent her credibility, as did her demeanor.
The support lent her credibility. So did her demeanor.
The support lent her credibility, and so did her demeanor.

I spell "demeanor" differently than you do. Is "demeanour" British? Interestingly, your sentence would work if you put "As" at the beginning. This is very old-fashioned, though.

As the support lent her credibility, so (also) did her demeanor.

That sentence changes the relationship of subordination between the two clauses, so it is a bit different in meaning from the trio of examples above.

Does the following sentence mean "the support" also lent her demeanour credibility?

The support lent her credibility, as did her demeanour. (Theranos scandal: Who is Elizabeth Holmes and why is she on trial? by Daniel Thomas)

No. The support improved her credibility, and so too did her demeanour. (We use British spellings in Canada.)

 

[Phaedrus]

No. The support improved her credibility, and so too did her demeanour. (We use British spellings in Canada.)

Nice catch, probus. I think 5jj and I were understanding Maybo's semantic suspicions differently from you, who read the question very carefully.

Maybo thought the second clause might mean that the support lent the woman's demeanor (in addition to the woman herself) credibility.

The real meaning of the second clause is that the woman's demeanor (in addition to the support) lent the woman herself credibility.

Yes, but it is better to have did before demeanour.

NOT A TEACHER

Maybo, your question made me do some Web research, which helped me to better understand the matter. I have made up these sentences.

1. "Sue speaks Spanish, as Joe does" or "Sue speaks Spanish, as does Joe." The second sentence is considered more formal.

2. "George received a good mark in math, as everyone did / as did everyone" is correct, but you must say something like "George will visit Paris this year, as he did five years ago." You cannot say "George will visit Paris this year, as did he five years ago."

a. Why? Because inversion ("did he" instead of "he did") works only when you have two contrastive subjects (such as "Sue" and "Joe" or "George" and "everyone").
