Navigating English Quantifiers: A Comprehensive Guide

In the realm of English grammar, quantifiers play a pivotal role in specifying quantity and defining relationships between items. This summary breaks down the usage of 'all', 'every', 'each', 'both', 'either', and 'neither', as discussed by the BBC Learning English team. By analyzing the context of choosing between two tablets, we can identify the subtle grammatical rules that dictate how these words function in sentences.

Grouping and Totality: All, Every, and Each

When we talk about the full amount or the total number of something, we often utilize 'all', 'every', and 'each'. However, their grammatical structures differ significantly:

• All: This quantifier refers to the total group and is followed by a plural noun and a plural verb. For example, the transcript notes, "all tablets have," illustrating that the noun and verb must remain in plural form. One can also use "all the tablets."
• Every and Each: These words are distinct because they are followed by a singular noun and a singular verb. The speakers clarify this by stating, "every tablet has" and "each tablet has." A crucial distinction to note is that while 'all' can take the article 'the', we "don't use the with each or every."

The Nuance of 'Each' vs. 'Every'

While they often seem interchangeable, there is a functional difference in how they are perceived. We use 'each' when focusing on the "individual members of a group." In the provided example, "each tablet is slightly different" highlights the specific features of one device versus another. Conversely, 'every' is used when considering the group as a whole or recurring instances. The phrase "every time you go out" demonstrates that the speaker is thinking about "all the times" collectively, rather than focusing on the individual uniqueness of each instance.

The Dual Perspective: Both, Either, and Neither

When dealing specifically with two items—such as the two tablets, the 'A-pick' and the 'Nega-2'—the language shifts to 'both', 'either', and 'neither'.

• Both: This refers to the pair collectively. The text states, "both tablets have similar specs," meaning this tablet and the other tablet. Note that the verb following 'both' is plural.
• Neither: This is the negative equivalent for two items, meaning "not this one and not the other one." The example "neither tablet is heavy" employs a singular verb, emphasizing the negation of both individual items.
• Either: Primarily used in questions and negative contexts, 'either' indicates a choice between options. Darren asks, "should you have either this one or that one?" to prompt a decision between the two available devices.

Advanced Usage: Using 'Of' and Pronouns

Grammar becomes slightly more complex when adding the preposition 'of'. Quantifiers like 'all', 'each', 'neither', 'either', and 'both' can be paired with 'of' followed by a plural noun phrase or a pronoun (e.g., 'them').

• Agreement Rules: When using 'each of the tablets', the verb remains singular ("each of the tablets has"). However, when using 'both', the verb must remain plural, as in "both of the tablets have."
• Contextual Equality: In scenarios involving only two items, "each of the tablets" and "both of the tablets" can convey the same logical meaning, though the grammatical agreement of the verb must still be strictly observed according to the subject used.

Conclusion

Mastering these quantifiers requires attention to whether you are addressing a group as a whole, individual members of that group, or a specific pair. By remembering that 'each' and 'every' demand singular verbs, 'all' and 'both' demand plural verbs, and 'neither' acts as a singular negative, speakers can navigate complex descriptions with clarity and precision.
