'ascosporic' originates from New Latin (formed from 'ascospora' / 'ascospore'), ultimately from Greek where 'askos' meant 'sac' and 'spora' meant 'seed' or 'sowing'.

'ascosporic' was formed in modern scientific English by combining the noun 'ascospore' (from New Latin/Greek roots) with the adjectival English suffix '-ic', producing a technical adjective meaning 'relating to ascospores'.

The original Greek roots literally meant 'sac' and 'seed'; over time they were combined in scientific Latin/English to refer specifically to spores produced in asci, and 'ascosporic' now means 'relating to or producing ascospores'.
