Ambiguous Assertion:
a statement is made, but it is sufficiently unclear that it leaves some sort of leeway. For example, a book about Washington politics did not place quotation marks around quotes. This left ambiguity about which parts of the book were first-hand reports and which parts were second-hand reports, assumptions, or outright fiction.

Of course, lack of clarity is not always intentional. Sometimes a statement is just vague.

If the statement has two different meanings, this is Amphiboly. For example, "Last night I shot a burglar in my pyjamas."
