airy-fairy
Lacking concrete substance
Airy-fairy describes something vague, impractical, or lacking substance—ideas or plans that float pleasantly but never touch ground.
The term is mildly dismissive: That's all airy-fairy nonsense.
More common in British than American English.
The rhyming reduplication reinforces the sense of whimsy without weight.
