It could be that they are including more than one person in the loop.Why would somebodysayssay " Include them in the loop" if they missed a person in the loop, why not "include him/her in the loop?
Noted.It could be that they are including more than one person in the loop.
Normally "them" is used when you talk about more than one person, but it can also be used in certain situations to talk about a single person, if you don't want to reference their gender, or if you don't know their gender.
For example on an internet message board like this, I could refer to you, ninjutsu, as "they" because I don't know if you are male or female.
Because modal auxiliary verbs* are followed by the bare infinitive.Noted.
Somebody is singular, why not "says"?
