Building on from [Zhen Lin's answer to "The grammar of ~かれ~かれ"][1],

Brief explanation of Zero-nominalisation:

> Nominalisation refers to the process of turning a word, or more generally a phrase, into a noun or noun phrase. For example, こと and もの are nominalisers for verb phrases. Zero-nominalisation is when the nominalisation happens without an overt word.

Previously being examined:

> 良かれ悪しかれ has a modern grammar rendition:

>> [a] よいにしろ悪いにしろ

> It is observed that the declension of the adjective is い instead of く as one would normally expect of い-adjectives when used with a verb.

> Zero-nominalisation accounts for this idiosyncratic behaviour.

<b>Question:</b> 

- Why does zero-nominalisation occur?

- Why do the adjectives in [a] not take on the `く` declension (along with deletion of the に　particle)? Would よくしろ悪くしろ still be grammatical?

- In what other instance(s) (if any) is zero-nominalisation appropriate?
