Well, it provides a 'verbification' format like ennoble (from, the noun, noble) which allows to get a new word for sleep also: slaf. Although it wasn't my intention to do that, it works. And plus, I don't like the look of inslaffen, so I dropped the i and used the beginning e.

I know this is old, but I rather like enslaffen, which is derived from the German word Einschlafen.

It should be singular; however, that only depends if you're talking about the organization as an organization or if the people who comprise of the organization.

My teacher told me that should/could/would also denote the future tense and with the addition of have, the future perfect. Should is used for first person and would for second and third persons and could for both. So a revision would be: "He would/could have done [this]".

I think it has to do with the fact that most is a superlative and not a comparative, as is more. Adjectives, and adverbs, have three forms: the positive (the base word), the comparative, and the superlative.

Positive: tall, many/much
Comparative: taller, more
Superlative: tallest, most

'It is what it is' is sentence with a noun clause (what it is).

I would say 'if that' because 'that' is relative pronoun that introduces a noun, adjective, or an adverb clause. When it's an adverb clause, it means a purpose or result, while 'if' is used for condition, i.e. "If I read now, I will be done with home work sooner."

@Warsaw Will,

Although you might find it stilted, 'whom does the new tax proposal really benefit' is correct. If we change the interrogative into the declarative (with emphatic verb form): 'the new tax proposal really does benefit whom (us/them/him/her/it/you).' or plainly keep the form and place the objective pronoun by its verb: 'does the new tax proposal really benefit us?'

However, don't clearly chop me down as a prescriptivist; I just prefer reasonable correctness. I am opposed to that antiquated rule of not splitting an infinitive and leaving a dangling preposition, for I see the English language as separate from Latin.
