adjective and noun - order inversion

[garonne]

As a native English speaker (more or less), I have a gut feeling that some adjectives come after the noun in English, and not before. Here are a few examples that sound wrong to me, and what I might replace them with

'mentioned' 'considered' and 'investigated' aren't adjectives in your examples. 'the study mentioned' is 'the study that was mentioned' etc.

(And just to confuse matters, you _can_ use them as parts of compound adjectives: the above-mentioned study, the recently-considered topics, the previously-investigated characters.)

What you're seeing here is not actually a noun + adjective + X construction, but rather a reduced relative clause construction, which is like a relative clause that lacks any relative pronoun. For example, your first case, As shown by the studied mentioned previously, the construction is a reduction of the fuller construction As shown by the study that was mentioned previously. So it makes more sense to consider these constructions as subsets of relative clauses, which traditionally follow the nouns they modify, than subsets of adjectives, which traditionally precede them. I agree that it sounds unnatural to put the past participle in an adjectival position, as in the considered topics, but other languages (Russian in particular) allow such relative-clause-like modifiers to go in exactly that position--especially when they're extremely short--so I'm not surprised they try to transfer it to English, especially since English past participles easily make the transition into standard adjectives (e.g., The man who was exhausted --> The man

My gut feeling agrees with the OP and with most of this comment.

as shown by the mentioned study -> as shown by the study mentioned previously/above

the considered topics -> the topics considered here/the topics under consideration

the investigated characters -> the characters investigated here

The OP's examples only work for me if the noun was in fact mentioned/considered/investigated very closely previous to this usage -- and even then the usage seems abrupt, truncated, amateurish,or foreign.

Thank you! That makes things a lot clearer.

Those are verb phrases used to modify nouns, and phrases and clauses come after the noun in English. It's one-word adjectives that come before.

[garonne]

Ah, okay. Thanks!

The participles 'mentioned' 'considered' and 'investigated' cannot be used as adjectives before nouns in idiomatic English unless, as noted in a previous comment, they are made into compound adjectives ('above-mentioned', etc.). However, there are many participles that have successfully made the transition to adjectives, for example

the loaded weapon,
the alleged offence,
the purported culprit.

Those are all perfectly acceptable idiomatic usages. I have no idea why this is the case for some participles but not for others.

[garonne]

Yeah… once I started to think about it I realised that lots of past participles ARE also perfectly valid adjectives, and that didn't help my confusion! It's interesting, though.

It's the correct word order for adjectives, but using past participles as adjectives is not normal and sounds rather German to me.
