Entediado vs. aborrecido
While both aborrecido and entediado can be translated as bored in English, they carry distinct nuances. Entediado refers to a simple state of being bored from lack of stimulation, whereas aborrecido often implies an additional feeling of annoyance, frustration, or being fed up.
Entediado
A2This word is the most direct and neutral translation for bored. It describes the feeling of weariness or mental fatigue that comes from having nothing to do, or from being engaged in a monotonous or uninteresting activity. It is a passive state that doesn't typically involve strong negative emotions like anger or irritation.
As crianças ficaram entediadas na festa de adultos.
(The children got bored at the grown-ups' party.)

(I am profoundly bored with this movie.)

(He yawned, clearly bored with the long presentation.)
Aborrecido
B1This word is more versatile and often stronger than entediado. While it can mean bored, it frequently implies that the boredom has led to feelings of annoyance, irritation, or being fed up. It suggests an active displeasure with the situation. Furthermore, aborrecido can also mean upset, annoyed, or even sad in contexts that have nothing to do with boredom.

(I'm bored and annoyed from waiting so long in this line.)

Summary
In essence, use entediado to describe a simple, neutral state of boredom from a lack of interest or activity. Use aborrecido when the boredom is coupled with annoyance or frustration, or to express being upset, fed up, or sad about something. If you are just un-stimulated, you are entediado; if a situation is actively bothering you, you are aborrecido.
