Surface Forms

coinsurance singular
coinsurances plural

Morphology

coinsurance = insurance (semi-transparent) = co + insurance

Morphologically 'co-' + 'insurance' is clear, but the specialized health-insurance sense 'insured's percentage share' is technical and not fully predictable for general learners.

Etymology

The word coinsurance comes from the prefix co- meaning 'together', the same co- you see in copay or cooperate, and insurance meaning protection, and in health plans it now means the part of a medical bill you 'share' with your insurer after the deductible. So, coinsurance is the percent of costs you and your insurer pay 'together'.
