What does reasonless mean?
Reasonless is an adjective describing conduct, beliefs, emotions, or situations that lack reason, logic, or justification. It is stronger and more absolute than merely being mistaken: a reasonless action appears to have no coherent motive, while a reasonless fear may seem disconnected from any actual danger. The word is especially associated with descriptions of violence, hatred, opposition, and behavior that appears unpredictable or indiscriminate. In ordinary conversation, irrational, unreasonable, senseless, and groundless are often more natural choices, but reasonless can convey a more literary or historical flavor. It may also suggest something so wholly without purpose that it borders on the senseless. The term is useful when emphasizing the complete absence of rational explanation rather than simply identifying an error of judgment or a poorly reasoned decision.

Where does reasonless come from?
Reasonless was formed in English by attaching the suffix -less to reason, the sense meaning that something is without something else. Reason itself comes through Old French raison from Latin ratio, a noun meaning “reason,” “method,” or “proportion,” related to the verb ratiocinari, “to reason.” Related English forms include rational, rationale, and ration, all reflecting the same Latin root.
