     She was really hungry, so the chicken and tarts served to divert her attention for a time. It was well I secured this forage; or both she, I and Sophie, to whom I conveyed a share of our repast, would have run a chance of getting no dinner at all: every one down stairs was too much engaged to think of us.

• Spelled every one when referring separately to every person or thing in a specified group: There were three patients and she helped every one . In such cases it cannot be replaced with everybody without changing the sense.
• Everyone takes a singular verb: Is everyone here?; Everyone has heard of it. However, similar to what occurs with collective or group nouns like crowd or team, sometimes a plural pronoun refers back to everyone which is also reflected in verb conjugations: Everyone was laughing at first, but then they all stopped. / Everyone has a smart phone nowadays, don't they?
• In colloquial speech it is common to say everyone is not X instead of not everyone is X (both of which may potentially have the intended meaning that most people are not X). The same is true of other universal qualifiers such as everybody, everything, all.

• (every person): everybody, the world and his wife
