1.
idle talk; empty talk; baseless chatter
Talk that is without substance, basis, or sincerity. Words that amount to nothing or lead nowhere.
2.
tall tale; fabricated story; made-up story
A story that is exaggerated or entirely made up, told to impress or entertain but not grounded in truth.
Composed of 空 (empty, hollow) and 話 (talk, story). The 空 here is the same as in 空っぽ (empty) and 空振り (a miss, a swing and miss), conveying the sense of being without substance.
The word can also be read as くうわ, which has a more formal and literary tone, though からばなし is the more common native Japanese reading.
