More inexperienced, immature, or lacking in sophistication than something or someone else.
Comparative form of 'callow,' from Old English 'calu' meaning bald or naked, originally describing young birds without feathers, then applied metaphorically to inexperienced people.
When we call someone 'callow,' we're using a 1,000-year-old bird metaphor—just like a featherless chick can't fly, a callow person can't navigate life's complexities!
