As per English Wikipedia:
Plurality voting is an electoral system in which each voter is allowed to vote for only one candidate, and the candidate who polls the most among their counterparts (a plurality) is elected.

La kandidato gajnis la plimulton/plejmulton de la voĉoj.
But what if they won a plurality, but not a majority, of the votes?
One would think that the solution lay in the difference between plejmulto and plimulto: taken literally, the former could be equivalent to absolute majority in the context of electoral systems, and the latter to relative majority (or plurality). But this distinction is not recognized by the dictionaries that I've checked. Vortaro, for instance, states:
So, how can you differentiate between these two concepts in Esperanto?
