Morphology

insufficient = sufficient (transparent) = in + sufficient

For learners who know 'sufficient', adding the negative prefix 'in-' straightforwardly yields the meaning 'not sufficient'.

Etymology

Insufficient comes from the common word suffice, which means 'to be enough', with the part in- meaning 'not'. So insufficient literally means 'not enough', which is why we use it when there is too little of something.
