A person who esteems or holds something in high regard; one who shows respect or admiration.
From 'esteem' plus the agent suffix '-er' (one who does something). A rare but grammatically regular formation indicating someone who practices esteeming.
Creating the word 'esteemer' is actually a really clever linguistic move—it suggests that respecting others isn't passive but an active choice you make, something you do rather than just feel!
