'information-abundant' originates from the combination of 'information' and 'abundant', where 'information' comes from Latin 'informare' meaning 'to inform', and 'abundant' from Latin 'abundare' meaning 'to overflow'.

'Information' evolved from the Latin 'informare' through Old French 'enformer', while 'abundant' evolved from Latin 'abundare' through Old French 'abondant'.

Initially, 'information' meant 'to inform or give form to', and 'abundant' meant 'overflowing'. Together, they now mean 'having a large amount of information'.
