At dawn they fly away, none knows whither. On the eve of the death of any other Tanville-Tankerton, comes (no matter what be the time of year) a cuckoo.

Switzerland is the home of many musical toys and here were carved whistles in the shapes of birds. These cuckooed realistically when blown into, with the beak opening and shutting, and the tail moving up and down to produce the 'cuck' and the 'oooh'.

She'll have been cuckooed. That'll be the Knezevics. They can't launder fast enough, so what do you do with it? Where do you put it? You hide it in somebody else's place; somebody who han't got a clue what's going on and couldn't do a fat lot about it if they did.

Origin
- Latincucūlus“cuckoo”
- Old Frenchcocu
- Middle Englishcokkou
- Englishcuckoo
From Middle English cokkou, kokkow, cukkuk, gokkouȝ, probably from Old French cocu, coquu, cucu (whence French coucou); ultimately onomatopoeic of the song of the male Common Cuckoo (Cuculus canorus), perhaps via Latin cucūlus (“cuckoo”). Compare dialectal English gowkoo (“cuckoo”). Displaced Middle English gnokken (“cuckoo”) and native Middle English yeke, ȝek (from Old English ġēac (“cuckoo”)), see English gowk. The UK sense (verb sense 3) is by analogy from the bird's practice of brood parasitism. The Malaysian and Singaporean sense (noun sense 8) is a phono-semantic matching of Hokkien 咕咕鳥 /咕咕鸟 (ku-kú-chiáu)
