The idea that between two alternatives should be used, and underneath for more than two, is a zombie rule with a family tree. It was apparently invented by Goold Brown in 1851, in his Grammar of English Grammars, to demonstrate his superiority over previous grammars that had “abused” between more than two alternatives. Between and below also have different meanings when it comes to the direction indicator. Look at the following examples, GrammarGirl has a full contribution. She explains that there is a difference between and between. She writes that her money was shared between her son and her daughter. In the various quotations provided by the OED to document the historical uses between more than two objects (the earliest is 971), these two are the most ironic, because they are (allegedly) the same author who contradicts himself: why did I bother? Indeed, so far, I have thought about going in and below only for the purposes of the introductory clause. (MSCD 2.46-.48 explains why the distinction between and enters this context is one of the great red herrings. Use instead only in between, but if someone insists, you don`t waste time discussing the topic.) These sentences are the same – but in the first sentence we call each of the three options (the green shirt, the blue shirt and the black shirt) – so we use the word in between. In the second sentence, we treat objects as part of a group (“these shirts”), so we use the word under.
Use the pennies if people or things can be considered collectively (i.e. as an undifferentiated group or mass) and not individually: on the other hand, you use “under” when talking about things that are not different elements or individuals; For example, if you talk collectively about colleges, you might say, “She chose the Ivy League schools.” If you`re talking about a group of people, also use “under”: a slightly more nuanced and perhaps updated view is that there are discrete and separate things for each one-to-one relationship. Among other things, for undefined collective uses, often with groups. So if Boswell correctly quotes Johnson, Johnson does not seem to have accepted his own advice in terms of decency and accuracy. Apparently, the good doctor`s ear went better from him – and that`s a good thing too, because it would have seemed ridiculous for him to use there. I was easily surprised to find that I apparently never wrote anything on this blog on which I should use, enter or below, if I list the parties to a contract, in the introductory clause or elsewhere. Here`s what MSCD 2.46-48 has to say: We can also use between, but not under, to connect times or numbers: as such, the rule covers most of the issues around these words, but it does not give the full picture, and the difference between these words is not always as clear.
