That is a combination of adverb describing a participial-adjective.
The following are examples of adjectives derived from verbs, hence participle+adjective.
Past completed/perfected participles
- painted door
- discarded food
- targeted audience
- folded business.
Present progressing participles
- running man
- traveling salesman
- closing sale
- folding chair
We could attach another adjective to describe how the fore-front adjective describes its noun.
- tall painted door
- smelly discarded food
- handsome traveling salesman.
OTOH, we could attach an adverb to describe how an adjective achieved its state
- quickly painted door
- unscrupulously discarded food
- fast-traveling salesman
- fast-moving van
- duly-noted heroism
Therefore, we could also use conjunctive adverbs to describe the adjective's achieving its state
- thus discarded food
- since folded business
- also-included reference letter
- hence-unrequited love
- thence-unrequited love
- likewise receded tumour
- otherwise-unnoticed genius
- she was then-unmarried Drew Barrymore
- the instead-of untainted replacement
- next-completed action item (vs next completed-action-item)
- she spilled the still-brewing tea.
Conjunctive adverb vs conjunctive adjective
- your nonetheless-perfected record should not be ruined
- your nonetheless-healthy lungs should not be subjected to stress anyway .
I did not expect this to be chosen the answer. I wrote this answer purely to remind (and educate those who did not know) of the grammatical elements of the situation.
My since-chosen answer obliges me to explain the difference between since-defunct vs now-defunct, by pointing out what it means to be a conjunctive adverb/adjective.
A conjunction connects two predicates. Therefore, a conjunctive adverb connects the action of the current new story to the effects of actions that took place in an existing story.
It is meaningless to have the conjunction in the story:
My since-reduced role in the company has been free from the burdens of responsibility
Unless it is preceded or followed by the likes of
having resigned as chair of the board
There is difference between jail time and walking free to say
My now-reduced role would not allow me the privilege of such decisions
My since-reduced role would not allow me the privilege of such decisions
When asked by the prosecutor in court
Did you over-see the release of toxic waste into the river after your resignation from the chair of the board?
Person 1: Prince Charming bent to kiss Snow White.
Person 2: Whereas the thus-broken spell continued to haunt her memories.
P1: Don't you know the messiah has come to save the world?
P2: But I'm afraid, such hence-perceived superstition removes from men their responsibility to save the planet from climate disaster.
