'He walked off embarrassed and sad'

Question

He walked off embarrassed and sad. (I can't remember where I found this sentence as I then just noted it without citing the source to ask later).

'Embarrassed' and 'sad' are functioning as Subjective complement? But as far as I'm aware, Subjective complements usually come after linking verbs or after certain types of verb.

If it's a participle clause modifying the whole sentence, then can we rewrite it as

Embarrassed and Sad, he walked off ?

What if he was just sad not embarrassed, then will it be correct to write it as

He walked off Sad ; Sad, he walked off ; and he walked off sadly?

So, the three questions I have asked are:

1. Are those two words subjective complement?

2. Is it a participle clause modifying the whole sentence?

3. Can the sentence be changed to aforementioned sentences? If not, please give the reason too.

(These three questions are interrelated So I thought it'd be better to just ask it at one go).

Answer 1

1. Yes, the two words are subjective compliments. "He" is the subject, and 'embarrassed' and 'sad' describe him. They don't describe his walk.

2. Yes, it is an example of a participle clause. There is no specified tense for the two adjectives - the tense is indicated by the verb in the main clause.

3. You could certainly put the adjectives first - most examples of participle clauses are written that way, for example:

Embarrassed and sad, he walked away.

Your last example of "he walked away sadly" is not quite right. Using the adverb 'sadly' would refer to his walk, not him. Arguably, a person with a sad walk is probably sad themselves. But grammatically, it isn't the same.
