What does curiouser mean?
"Curiouser" is a famously nonstandard comparative form of the adjective "curious," meaning "more curious" or "stranger." In ordinary English, three-syllable adjectives like "curious" form their comparative with "more" rather than the suffix "-er," so "curiouser" violates standard grammatical rules. Its enduring place in the language comes almost entirely from Lewis Carroll's Alice's Adventures in Wonderland (1865), where Alice cries out "Curiouser and curiouser!" as she undergoes increasingly strange transformations. Because of that single celebrated utterance, the word survives today as a literary curiosity: writers and speakers reach for it playfully, usually in the fixed phrase "curiouser and curiouser," to signal whimsy, escalating strangeness, or a deliberate nod to Carroll. Using it outside quotation or allusive context would strike most readers as an error, so it belongs firmly to the realm of humor and homage rather than neutral description.

Etymology of curiouser
The element "curious-" derives from Latin curiosus, meaning careful or inquisitive, itself formed on cura, meaning care, via Old French curieux. The suffix "-er" is the native Germanic comparative ending normally reserved for short adjectives. Lewis Carroll combined the two in Alice's Adventures in Wonderland (1865), creating a deliberately childish, rule-breaking comparative that has kept the word alive ever since.
How curiouser is actually used
"Curiouser" is deliberately ungrammatical in standard English — the correct comparative of "curious" is "more curious," since adjectives of three syllables do not take the -er ending. It should be treated as a literary or humorous allusion to Carroll rather than acceptable everyday usage.
Easily confused with curiouser
