Frequently Asked Questions
If 'clave' means 'key', why is it always feminine ('la clave') when talking about passwords, but 'llave' (physical key) is also feminine?
'Clave' (password/code/crucial factor) comes from the Latin word for key (*clavis*), which was feminine. 'Llave' (the physical object you use to open a door) also comes from the same root. So both are feminine, but they refer to different types of 'keys': 'clave' is usually abstract (code, factor), and 'llave' is physical (door key).
Does 'clave' change form when used as an adjective?
No. This is a great thing to remember! When 'clave' describes a noun (meaning crucial or essential), it is 'invariable,' which means it always stays 'clave.' You can say 'el punto clave' (singular, masculine) and 'las preguntas clave' (plural, feminine).
