What I have learnt so far, an adverb can be placed adjacent to a verb. For example,

It is directly passed to the next block.


It is passed directly to the next block.

I found a sentence as follows.

It is passed unchanged to the next block.

Why is it possible to place an adjective "unmodified" here? And what is its function?

Can I rephrase it as follows?

It is passed unmodifiedly to the next block.

  • In, say, I drink neat whisky, it's obvious that the highlighted word is an adjective. Maybe it's not so obvious that Neat whisky is drunk in my house AND Whisky is drunk neat in my house are BOTH ALSO adjectival, but so far as I'm concerned that's all there is to it. And in the same vein, unchanged / unmodified are also adjectives in your context (and to a first approximation, unmodifiedly simply isn't a valid term in English). Jan 12, 2021 at 18:31

    "Unchanged" is an adjective. It's predicative here, i.e. even though it is located in the verb phrase as a modifying adjunct, it refers to the subject "it". Its function is thus 'predicative adjunct'. The same applies to your example with the adjective "unmodified".

  • @BillJ: Thank you for your insightful comments. One more question, is it possible to swap the passed and unmodified without changing the meaning? For example, It is passed unmodified to the next block is rephrased as It is unmodified passed to the next block. Jan 13, 2021 at 1:32
  • @ArtificialStupidity No. adjectives functioning as predicative adjuncts only occur after the verb, never before.

It is passed directly ...

the "directly" is an adverb telling you how it is passed, so an adverb modifying the verb.


It is passed unmodified

the "ummodified" is an adjective telling you about it, so an adjective.

There's no grammatical reason to object to placing it after the verb.

I wouldn't want to read about passing it unmodifiably unless there were some technical reason to describe the passing that way.

(This is a less technical version of the comment from @BillJ .)
