CE - Theh
The Castilian Spanish pronunciation of the letters "CE" is "theh" as in the beginning of the English word theft.
For example, you would pronounce cerca (rear) as "thehr-kah".
The letters CE are pronounced THEH
To remember this we use the following mnemonic:
The Church of England (CE) reported a theft (CE=theh) of all their seats, so people had to sit on the floor.
