Morphology

mortality + rate

The phrase combines 'mortality' (deaths in a population) with 'rate' (frequency per unit), so its meaning — the number of deaths per unit of population per time — is directly and compositionally derivable from the constituents. This is a common, cross-linguistic measurement pattern (noun + rate) and would be understandable to a learner who knows both words, despite being somewhat technical.

Etymology

Mortality rate comes from simple counting: mortality means death and rate means how often or how many in a group. So it is the 'number of deaths' in a group of people, which is why we use it to show how common death is in a population.
