Absolutely

Used for emphasis to mean completely and totally; used to express strong agreement or confirmation.

Derived from 'absolute' plus '-ly', entering English in the late 14th century from Latin 'absolutus' meaning 'freed, unrestricted'. The Latin comes from 'absolvere' (to set free, acquit), combining 'ab-' (away from) and 'solvere' (to loosen, untie).
