Agacé vs. irrité vs. énervé
French offers a gradient of words to describe being bothered, ranging from mild nuisances to actual anger. While agacé, irrité, and énervé are often used interchangeably in casual conversation, they possess distinct nuances regarding intensity, physical sensations, and emotional states.
Agacé
B2This word describes a mild to moderate feeling of being bothered or pestered. It is often used when repetitive, minor nuisances—like a ticking clock, a buzzing fly, or someone nervous tapping their foot—start to get on your nerves. It suggests that your patience is being tested, but you are not necessarily angry yet.
Elle est agacée par le bruit de la mastication de son frère.
(She is annoyed by the sound of her brother chewing.)
Le comportement enfantin de son collègue a fini par l'agacer.
(His colleague's childish behavior eventually annoyed him.)
Je suis un peu agacé de devoir répéter la même chose trois fois.
(I am a little bothered having to repeat the same thing three times.)
Irrité
B1This term implies a sharper, pricklier sensation than agacé. It describes a state of impatience or a bad mood where one's tolerance is very low. Uniquely, irrité is also the standard medical or physical term used to describe inflammation of the skin, eyes, or throat.
Le chlore de la piscine a irrité mes yeux.
(The chlorine in the pool irritated my eyes.)
Sa réponse sarcastique a visiblement irrité le directeur.
(His sarcastic answer visibly irritated the director.)
Il est très fatigué, donc il est facilement irrité ce soir.
(He is very tired, so he is easily irritated tonight.)
Énervé
A2This is generally the strongest of the three in changing a person's mood. While it literally relates to nerves, énervé usually means someone is angry, mad, or highly worked up. If someone says they are énervé, they are no longer just mildly bothered; they are visibly upset or furious.

(Mom was really angry when I broke the vase.)

(Don't talk to him now, he is too worked up to listen.)

(Traffic jams make me angry every morning.)
Summary
In short, think of these words as a scale of intensity and type. Use agacé for mild annoyances or when you feel pestered by repetitive things. Use irrité for physical soreness or a sharp, prickly lack of patience. Use énervé when the situation escalates to actual anger or when someone is visibly distressed and worked up.
