What does loonier mean?
“Loonier” is the comparative form of the informal adjective “loony,” meaning crazier, more eccentric, more irrational, or more absurd than something else. It is especially common in speech and informal writing, where it can express amusement at an unusual idea or mild disapproval of irrational behaviour. Because it compares two people, actions, or situations, it normally appears in a construction such as “loonier than” or with another intensifier, as in “even loonier.” In more formal contexts, alternatives such as “more eccentric,” “more irrational,” or “more absurd” may be preferable. The word ultimately comes from “lunatic,” an older term associated with the Latin luna, meaning “moon.” Its modern meaning reflects a playful extension of ideas of madness and irrationality rather than any literal connection with lunar activity. “Loonier” is therefore expressive and conversational, and its force often depends on context: it may sound humorous and affectionate, or dismissive and insulting.

Etymology of loonier
The word descends from the informal English adjective “loony,” which was formed from “lunatic” or related forms. “Lunatic” comes from Latin lunaticus, derived from luna, “moon,” and originally referred to someone affected or “struck” by the moon. English later used “lunatic” for someone regarded as insane, and “loony” developed as a more colloquial expression with that meaning.
