“Cuckoo” ( cuco, cuclillo) you may know. Perhaps you have a cuckoo clock (reloj de cuco) in your house.
“Cuckoo” has other uses. If someone is cuckoo, he is crazy (loco, chiflado).
Some people live in “cloud cuckoo land” (or live on another planet) meaning that the person´s ideas are totally unrealistic and impractical.
Examine these examples:
• Mr. Podemos lives in cloud cuckoo land (…vive en las nubes o vive en un mundo de fantasía).
• Donald is a bit cuckoo (loco).
