Etymology
The word 'co-discoverer' is a modern English compound built from established morphemes. The prefix 'co-', of Latin origin, signifies joint action. It is attached to the agent noun 'discoverer', which itself is formed from the verb 'discover' and the agent suffix '-er'. The verb 'discover' carries the literal sense of 'un-covering' something hidden. Therefore, a 'co-discoverer' logically denotes one who jointly performs the act of uncovering or finding something new with another.
Analysis
Structure: co (together) + discover (find) + er (agent)
- co: from Latin com- (together, with), a prefix indicating joint action or partnership.
- discover: from Old French descovrir, based on Latin dis- (expressing reversal) + cooperire (to cover). The core morpheme here is 'cover', with the prefix 'dis-' reversing its meaning to 'uncover'.
- er: from Old English -ere, an agent noun suffix indicating a person who performs an action.
