How to actually learn idioms

An idiom is a phrase whose meaning is fixed by convention, not built from its words. That is why a word-for-word translation fails: "spill the beans" has nothing to do with its literal words, it simply means to reveal a secret.

Learn a few at a time, not a whole list. Pick the ones you keep running into, say them out loud in a real sentence, and you will remember them far longer than by drilling flashcards.

The most reliable way to absorb idioms is to meet them in context, again and again, in things you actually read. Parallel text and audio let you catch an idiom in a real English sentence and check what it means without breaking your reading. That is what reading in Lingo7 is built for.
