When is "some" used as plural and when is it used as singular? I am trying to find out if this question is correct. Did Wang Bo used to be awkward?
Should I write "use to be" instead of "used to be," or is "used to be" correct in this sentence? Here is a question that has been nagging me for a few years: Which is the right usage: "Didn't used to" or "didn't use to?" Examples: We lived on the coast for years but we didn't use to go to the differences - Didn't used to or didn't use to? - English Language ... 5 For the sense "not used anymore", one could say "It is used no more".
used mbp, ngrams for no longer used,used no more,not used any more,not used anymore,not used any longer [listed in descending order of frequency and shown in first figure below] shows that usage of no longer used has increased substantially in the last 200 years or so. If "used to" is a set idiomatic phrase (i.e. not a tense), then why would it change its form from "use to" to "used to" for the sentence as it does in the positive? The animals were frequently used as a model organism in the 19th and 20th centuries, resulting in the epithet "guinea pig" for a test subject, but have since been largely replaced by other rodents such as mice and rats. Why is "guinea pig" used as the colloquial term for test subjects?
