Final answer:
In the AIS dictionary, semicolons indicate that a term has multiple definitions.
Step-by-step explanation:
In the context of the AIS dictionary, semicolons indicate multiple definitions for a single term.
This means that when a semicolon is present, the term being defined has more than one meaning or interpretation, which the dictionary will list sequentially.
Traditionally in English grammar, semicolons are used to connect two independent clauses that are closely related or when the second clause restates the first. However, this particular use in a dictionary's format is a bit different from standard grammatical practice.
