City – la ciudad
(Pronounced see-oo-dahd)
To remember that city is pronounced see-oo-dahd (ciudad) in Latin American Spanish, use the following mnemonic:
She was leaving the city and her dad for the first time. "See you Dad!" (ciudad) she said.

Ciudad is feminine, so it’s la ciudad. Imagine a city with a lady on top of every building:

La ciudad es muy grande y tiene muchos parques.
(The city is very big and has many parks.)
Vivo en una ciudad cerca del mar.
(I live in a city near the sea.)
La ciudad se ve hermosa por la noche.
(The city looks beautiful at night.)
