Morphology
hematocrit = hemato + crit
Formed from technical combining forms (hemato- + -crit) that are not productive or familiar to average learners, so the meaning cannot be reliably derived from the parts.
Etymology
Hematocrit was originally the name of a medical tool. It comes from the parts hemato- ('blood') and -crit ('judge' or 'separate') — think of critic as a 'judge' — and the hematocrit tool 'judges' blood by spinning it to separate red cells from plasma, so it measures blood cell levels.
