But did you know that "concert" is also a verb? (You spell it the same as the noun, "concert," but you pronounce the verb "kun SERT.") To concert things is to work on them together, or to arrange them together. You can concert with someone, or concert with someone on a project or a plan, meaning you work as a team.
We hardly ever use that verb, "concert," but we do often tweak it into an adjective, "concerted." When we talk about concerted efforts, or concerted action, or concerted schemes, we're talking about efforts that people made as a group, or action that people took as a group, or schemes that people planned and pulled off as a group. If you're working in harmony with other people, then you're making a concerted effort.
And you wouldn't like it if someone came along and disconcerted your efforts!
If some person or event disconcerts you, or disconcerts your plan or your work, then it messes you up, confuses you, or messes up your plan or your work. It throws everything out of whack. It interrupts your progress or stops you from getting things done.
You feel disconcerted when you're suddenly bothered and confused by something, and you're unable to keep doing what you were trying to do. For example, you might be doing your math homework, zipping right along and answering every question easily, but then a really hard question disconcerts you. You're disconcerted. You're forced to stop, and think, and deal with your confusion. "How should I even approach this problem?" you might ask yourself, disconcerted.
Disconcerting things are weird, confusing, and uncomfortable. It can be disconcerting to see your teacher outside of school; you weren't expecting it, and it feels awkward. It can be disconcerting to find a hair in your toothbrush: especially if it's the wrong color!
To sum this up, say that you're disconcerted when you're suddenly confused and thrown off, unable to continue what you were trying to do. And say that things are disconcerting when they throw you off: when they're strange and unsettling.
