What does nonsensical mean?
Nonsensical describes words, ideas, actions, or situations that lack a coherent, sensible, or logical meaning. It is often used when something seems so confused or unreasonable that it appears absurd or impossible to take seriously. A statement can be factually understandable yet still be criticized as nonsensical when its reasoning is incoherent, its conclusions do not follow, or its purpose is unclear. The word frequently appears with language, behavior, claims, proposals, and ideas, as in “nonsensical behavior” or “a nonsensical claim.” It is more emphatic than words such as strange or unclear, because it suggests a fundamental absence of logic rather than a simple lack of information. Nonsensical is especially useful when describing something that is not merely surprising or unusual, but genuinely unreasonable or without meaning.

Sometimes a sentence can use perfectly familiar words and still say absolutely nothing: that is the peculiar power of the nonsensical.

Etymology of nonsensical
“Nonsensical” was formed in the 19th century by combining “nonsense,” from the sense of words or ideas lacking meaning, with the adjective-forming suffix “-ical.” Its underlying root is the Latin “sensus,” meaning perception or feeling, which also gives rise to words such as “sensation,” “sensible,” and “sensitive.” The modern form reflects the later English sense of “nonsense,” a word of uncertain origin that had come to mean foolish or absurd language.
