3.8 Semantic ambiguity
Two types of ambiguity can be distinguished: static ambiguity and dynamic (e.g. time-related) ambiguity. The difference is determined whether that sentence is static or dynamic.
An example of static ambiguity:
• “Boston is a city in both the United States and the United Kingdom”.
An example of dynamic ambiguity:
• “Bush is inaugurated as (the) president of the United States.”, because George H. W. Bush was inaugurated in 1989, and his son George W. Bush was inaugurated in 2001, and re-inaugurated in 2005.
