What does unaccountably mean?
Unaccountably is an adverb meaning in a way or to an extent that cannot be explained or accounted for. It commonly appears with words such as “high,” “large,” “low,” or “absent” to describe a result that is so striking, unusual, or disproportionate that no adequate explanation has emerged. For example, an instrument might begin drifting unaccountably, or a population might experience an unaccountably large decline. The word is more specific than “surprisingly”: it implies not merely that something was unexpected but that its cause or significance remains mysterious. Although commonly associated with puzzling measurements and events, it can describe any inexplicable manner or degree. In everyday prose, a simpler alternative such as “inexplicably” may feel more direct, but “unaccountably” has a formal, slightly literary quality that suits analytical or narrative writing.
adverbIn a manner or to a degree that cannot be explained or accounted for. It is used especially of events, results, or magnitudes for which there is no satisfactory explanation.

"The river rose unaccountably during the night, leaving the village unsure what had caused the flood."
"The instrument began drifting unaccountably, making its readings increasingly difficult to trust."
"For reasons no one could explain, the old bell rang unaccountably in the middle of the night."
A mystery can be measured, but “unaccountably” reminds us that measurement does not always provide an explanation.

Where does unaccountably come from?
The English adverb was formed by adding the suffix “-ly” to “unaccountable,” which combines “un-” with “accountable.” “Accountable” derives from “account” plus the suffix “-able,” while “account” comes through Anglo-Norman French from Latin computare, meaning “to calculate.” The same Latin root underlies related English words including “count,” “accountability,” and “accountant.”
How unaccountably is actually used
The word is neutral to formal and suggests that no satisfactory explanation is available. It is stronger and more specific than simply saying that something was unexpected, and it is especially natural when describing striking changes, magnitudes, or inexplicable events.
