Welcome back, FF fans! The Grammar Cop has found a plethora of plural misdemeanours for your perusal this week. 😄

1. Even SARS-CoV-2 – itself a phenomena of nature – must adhere to these rules.
2. Standing in my kitchen later that Saturday afternoon, I talked with my roommate, Steve (a pseudonym), checking in on how each of us are getting along in quarantine.
3. Doctors called her a healthy carrier – someone infected by a disease but who display little or no symptoms of the disease, which means they often go on to infect many other people.

And the corrections:

1. Here’s a common error made by many otherwise-astute writers. The word “phenomena” is plural. The singular form is “phenomenon.” Obviously this sentence is calling for the singular: Even SARS-CoV-2 – itself a phenomenon of nature – must adhere to these rules.
2. If the subject of the clause is singular, as in “how each of us are getting along…,” then the verb that follows must be singular to agree with it: how each of us is getting along in quarantine.
3. Same as the previous. The subject of the clause is singular: “someone infected by…” Therefore the verb that follows it must be singular as well: someone infected by a disease but who displays little or no symptoms of the disease… (If you’re uncomfortable about the plural “they” after that, you could reword the sentence, perhaps like this: Doctors called her a healthy carrier – someone infected by a disease but who displays little or no symptoms of it. Such carriers often go on to infect many other people.)

You can see that the Grammar Cop has been reading a lot of COVID-related material. Or is that materials? Hmm… Stay safe, everyone!
