Something or someone that enriches or makes something richer or better.
From enrich (from en- + rich, via Old French) + -ener (rare variant suffix). This archaic form shows how English experimented with different agent suffixes before settling on -er.
This word is almost completely forgotten, replaced by 'enricher,' but it reveals how English constantly tries different word-building patterns—some survive and some disappear based on what just sounds right to speakers.
