Agreement Ada is Sentence-Town's protocol officer.

This is the quietly-essential role that makes sure the mayor and the chief of operations are matched in form. Singular subject + singular verb. Plural subject + plural verb. The rule sounds simple. In practice, it has many tricky cases — and Ada handles them all.

04 Agreement Ada
Agreement Ada beat 4 of 5

Ada grew up in a diplomatic family. Her parents had both been protocol officers in the kingdom's foreign-ministry — civil servants who specialized in the correct forms of address for various diplomatic interactions. The kingdom had had a particularly elaborate protocol tradition, and Ada's parents had been responsible for making sure every diplomatic letter, every formal meeting, every ceremonial occasion used the correct titles, forms, and sequences.

Ada had grown up learning, viscerally, that form-matching mattered. A letter addressed To His Royal Highness Prince X was different from a letter addressed To Prince X. The form had to match the relationship. If the form was wrong, the diplomatic relationship was damaged.

She recognized, by fourteen, that English subject-verb agreement worked the same way. The form of the verb had to match the form of the subject. Mismatched forms damaged the sentence — they sounded wrong to a careful reader and signaled either carelessness or ignorance. A protocol officer's job, in either domain, was to enforce the matching.

In her classroom, she begins every first-day lesson the same way. She holds up a small balance scale (a teaching prop — two small pans on either side of a fulcrum). On the left pan she places a small token labeled Subject. On the right pan she places a small token labeled Verb. She turns to the class. She says: "My job is to make sure these two are balanced. Subject form on one side. Verb form on the other side. They must match. If they do not match, the sentence does not balance."

She demonstrates. She writes on the board: the dog barks. She points at the dog. She says: "Singular subject." She points at barks. She says: "Singular verb (barks is the third-person singular present form). Matched. Balanced."

She writes: the dogs bark. She says: "Plural subject. Plural verb (bark is the plural form). Matched. Balanced."

Then she demonstrates tricky cases.
