Forms

speculātiō f (genitive speculātiōnis); third declension[1]

Etymology

It is from Latin speculor (“to watch, spy out”) + -tiō,[2][3][4] which comes from specula1 (“lookout”) and ultimately from speciō (“to look at”).[1]

Earliest recorded meaning

It is first found in Ausonius (c. 310–394 AD),[5] whose Mosella (326) uses it for viewing or beholding: suis fruitur dives speculatio terris “rich viewing enjoys its own lands”.[3]

Semantic evolution

Ammianus Marcellinus uses it for military reconnaissance, and in the plural for scouts' reports.[2][3][6] The Vulgate has it for a lookout post (Hosea 5.1),[6] and Gregory the Great writes of a turris speculationis, a watchtower.[2][3] Augustine and Boethius use it for contemplation.[6][2][3]

In medieval British Latin it meant observation, witnessing and contemplation, and also served as a gloss on the name Sion.[7] English borrowed it in the late 14th century, from Old French and directly from Late Latin, as speculation.[4]
