Morphology

undercount = count (transparent) = under + count

Formed by the productive prefix 'under-' meaning 'too little' plus 'count,' producing the expected meaning 'a count that is too low.'

Etymology

Undercount is made from the parts under ('less' or 'below') and count ('to number' or 'to add up'). Think of someone stopping too soon when they count people so the total is too small, and an undercount is a total that is less than the true number.
