'Disconcerted' describes a person's feeling, while 'disconcerting' describes something that causes that feeling (e.g., 'His behavior was disconcerting').
Reserve this word for describing someone's internal state of confusion or unease, not for describing the cause itself.
From French *disconcerter* (to upset), derived from *dis-* (undoing) + *concerter* (to arrange, harmonize), from Latin *concertare* (to contend). First recorded in English in the late 17th century.
Commonly used in formal or literary contexts to describe emotional discomfort. Less frequently used in casual conversation.
