The word "perturbing" is derived from the verb "perturb", which originated in Middle English from the Latin word "perturbare".
In Latin, the prefix "per-" meant "through, thoroughly", and "turbare" meant "to disturb". Thus, when combined, "perturbare" meant "to thoroughly disturb".
Over time, the word "perturb" made its way into Middle English, where it continued to retain its meaning of "disturb" or "agitate". By adding the suffix "-ing" to form "perturbing", it became the present participle form of the verb, describing an ongoing or continuous state of disturbing or causing anxiety.
