How it works

English 'measurement', 'observation' and 'achievement' have Spanish counterparts built from verbs by rule. Learn the endings and you stop looking such words up.

-ción is the commonest, and always feminine: medir → la medición, observar → la observación. In the plural the written accent disappears: las observaciones.

-miento is masculine: conocer → el conocimiento, descubrir → el descubrimiento, crecer → el crecimiento.

-dad and -eza build a noun from an adjective rather than from a verb: regular → la regularidad, pobre → la pobreza. Both are feminine.

How the rule settles in your head

A rule is not memorized from an explanation. It is memorized from an attempt to use it and a mistake — that is why the app delivers it mixed in with words, not as a separate lesson: it resurfaces exactly where you forgot it.
