We have two phrases structures:
- 'the nicest in my school'
- 'the cleanest in my house'
These phrases can act as nouns or adverbs:
- 'He is the nicest in my school.' - noun phrase.
- 'She cleaned the cleanest in my house.' - noun phrase -or- adverb phrase. Meanings (noun phrase:
"She cleaned the cleanest [omitted thing] in my house; adverb phrase:
"She cleaned most, comparatively, [to the other omitted things] in my house.").
So these are the disambiguations I suggest:
- 'She cleaned cleanest in my house.'
- 'She cleaned the cleanest, in my house.'
- 'She cleaned the-cleanest-in-my-house.'
Isn't 1. a better disambiguity to simply say she, herself, is the best cleaner? Because in 2., 'the cleanest' can also be a noun phrase and in 3. 'the-cleanest-in-my-house' is in emulation of another person?
About 1: 'in the house' is a location set by the adverb so there is an ambiguity; however, when setting groups by the adverb (i.e., 'of my house'), 1. is sufficient, right?
- She cleaned, the cleanliest in my house. - Uses allusion to suggest that the subject, herself, is the cleanliest person.
- She cleaned [the] cleanliest in my house. - Shows that 'the' is unnecessary. Perhaps, for example, it is added for euphonic purposes.
