tedi

The grammar runs the opposite way to English feelings-talk: the boring thing is the subject and the bored person the object, so it is la filmo tedas min, never mi tedas la filmon unless you really are the one sending the film to sleep. The pattern shines in the impersonal present: tedas min atendi, waiting bores me, with the infinitive as subject. You will occasionally meet tedas al mi by analogy with plaĉi, but the accusative is the classical, safe construction. Teda is boring, tedulo a bore, and enuo, boredom felt from the inside, is the other half of the story.
