ampliative

Ampliative (from Latin ampliare, "to enlarge"), a term used mainly in logic, meaning "extending" or "adding to that which is already known".{{EB1911|inline=y|wstitle=Ampliative|volume=1|page=893}}

This terminology was often used by medieval logicians in the analyses of the temporal content of their subject terms.{{Cite book |last=Øhrstrøm |first=Peter |title=Temporal Logic: From Ancient Ideas to Artificial Intelligence |last2=Hasle |first2=Per |publisher=Springer Science & Business Media |year=2007 |isbn=978-0-585-37463-5 |location=Dordrecht |pages=39 |language=en}} There were three rules outlined in its usage:

1. Common terms in a sentence only represent present things when they stand with a non-ampliating verb about the present;
2. A common term standing in a sentence with a verb about the past is able to stand for present and past things; and,
3. The common term standing with a verb about the future can indifferently stand for present and future things.

There are Roman texts that refer to it as ampliatio.{{Cite book |last=Friedman |first=Russell |title=The Medieval Heritage in Early Modern Metaphysics and Modal Theory, 1400–1700 |last2=Nielsen |first2=L.

In Norman law, an ampliation was a postponement of a sentence in order to obtain further evidence.
