Etymology
It is borrowed from Old French speculacion (“close observation, rapt attention”) and directly from Late Latin speculātiō, contemplation, a spying out,[2][3] from the past participle of Latin speculārī, to spy out, observe,[2][3] from specere, to look at (see speculate and spectacle).[2]
Earliest recorded meaning
Contemplation or profound study of a subject: about 1374 in the OED, the late 14th century in Etymonline.[4][2]
Semantic evolution
Pursuing truth by thinking is from the mid-15th century,[2] and in Middle English it could also mean theory as opposed to practice.[2] The faculty of sight (1471) and seeing or looking (1509) are obsolete senses.[4] The disparaging sense, mere conjecture, is from the 1570s.[2] Buying and selling in the hope of profiting from changes in market value is from 1774,[2] with the short form spec from 1794.[2]
