Morphology

cointegration = cointegrate (semi-transparent) = co + integrate + ion

The noun is formed by the regular nominalizing suffix '-ion' added to the verb 'cointegrate'.

Etymology

The word cointegration is made of co- meaning 'together' and integrate meaning 'to make whole' or 'combine'. So cointegration describes two or more time series that 'stay together' over the long run, moving as if joined even when they differ for short times.
