Etymology

It is from labor “toil” with the verbal suffix -ō.[2][1][3]

Earliest recorded meaning

The OLD's first citations are from Plautus, of physical toil and of anxiety.[2] Köbler dates Plautus c. 250–184 BC.[4]

Semantic evolution

It meant to perform physical work, toil, as Cicero's ploughmen who work for themselves, and to exert oneself, take pains, as in Terence's nē labōrā “don't trouble yourself”.[2][5][6] It meant to be under strain, of troops hard pressed in battle, as in Caesar, of ships in a storm, of the moon in eclipse, and of plants.[2] It meant to be in trouble, to suffer from a defect, to be ill, as in Cicero, and to be anxious, as in Plautus.[2] Transitively it meant to work at something, as in Virgil.[2]

In Ecclesiastical Latin it meant to labour, toil, be wearied.[7] It survives in Italian lavorare “to work” and French labourer “to plough”.[1] Through Old French laborer it is the source of English labour as a verb in the late 14th century, and English laboratory comes from Medieval Latin labōrātōrium.[3]
