der, die oder das Code?

Exception

-e → die

Usually 85.6% of the 2,894 common nouns ending in -e take die.

Code breaks this rule: it is der Code, not die Code.

Masculine -e nouns are mostly people and animals (der Junge, der Kollege, der Löwe). Learn der Name and der Käse as pairs.

Other exceptions der Glaube, der Junge, das Ende, der Name
