Now, Let us consider the difference between the two phrases, “All of this” and “All of these”. The difference between the two phrases is determined by where they are used, what and how they are used to refer to something.

All” in the both context is used to refer to nouns, whether countable noun or collective noun.

This” is used to refer to a singular noun that is countable while “these” is used to refer to plural nouns that are countable. “All of this” is used to refer to multiple individual items when they are being referred to collectively. The use of the phrase does not stripe the items being referred to off their individual identity; it merely refers to them as a single whole or as a group. The Phrase, ‘this‘ ordinarily refers to a singular item or noun. And now, the phrase “all” that is ordinarily used to refer to large number of items or plurals is brought into the same context with another phrase indicating singular.

This is exactly the situation here. The summary of what happens is that the items are being referred to as a single whole or group while they still maintain their identity as individual item. Here is an explanation in an instance; Mr. Peter walked into his son’s room and instructed him thus: “stamp of all of this book in your shelf”. The use of the Singular “this” and the plural “all” to refer to the books means that he refers to all of the books as a collective item while still maintaining their individual identity. Mr. Peter was simply referring to every single book in the shelf.

All this or all these

On the other hand, when one says, “All of these“, it is used to refer to multiple individual items which forms part of the whole but does not refer to everything.. Here, the several items are being identified and referred to separately in their individual identity, and then, the phrase “these“, rather than identifying them singly, refers to them in a pluralized form as it ought to be. An illustration in sentence goes thus: Mr. Peter walked into his son’s room pointing at certain books specifically he said to him, “All of these books must be stamped before the end of today“. Now, this example does not refer to all of the books in the shelf but to the ones Mr. Peter Specifically pointed at. Now, which of the phrases is correct, “all of this” or “all of these”?

From the foregoing, it could be seen that the both phrases are correct as long as they are being used in the appropriate context. Clearly, the word “all” is used to refer to a whole or the entirety of something. It is clearly a plural, yet, it can be used whether the items being referred to are particularly identified or whether it refers to all without more or less. Even when it refers to the items particularly identified, it refers to all of them as were identified, hence while the word is appropriate for both phrases.

Now, are the both phrases singular or plural?

The answer to this is straightforward. The word, “there” is the plural form of the singular, “this“. Therefore, “all of this” refers to and qualifies as a singular while “all of these” refer to and qualifies as a plural. The major determinant as to whether the two phrases are either singular or plural is the relevance of the words “this” and “these“. Recall that “all of “this” when used, preserves the individual identity and relevance of the items being referred to, even though it refers to them in whole. Therefore, the items still maintain their singularity.

On the other hand, the phrase “all of these” simply refer to a number of particularly identified items as a group that they are. In further buttressing the use of the both phrases, as it should be in English Language, when a singular form is used for a noun, the action word following it will be appended with an “S”, whereas if the noun used is in its plural form, the accompanying action word must not be appended with an ‘S‘. An illustration will explain this better. See for instance, “the book makes me laugh”. “The “make” here has an ’s’ and that is how it should be. It would be grammatically wrong to Say that “the book make me laugh”.

The noun here in question is “book” and it is in its singular form. Now, bringing it down to the phrases that are being considered “this” is a singular form. “All of “this” is still in its singular form. By way of Illustration, one can correctly say thus, “All of this book makes me laugh. It goes the other way the round when considering the plural form. Thus, it will be correct to say, “All of these books make me laugh”. Did you notice the difference? When you Use the plural form of the phrase, the action word following afterwards is not to have an “S”. This further elaborates the syntax (set of rules) governing the use of the two phrases being considered.

Further, in a Colloquial context, the preposition, “of” may be done away with and the purpose and meaning of the phrase will still be maintained. By illustration, what is meant here is that in a less formal setting, one can use “All this” and “all these” (dropping the “of”) instead of “all of “this” and “all of these”. To For instance, “All these are mine”, “All this is mine”. They are the same thing, although the latter is conveniently used in a conversation of common parlance.
