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: Толгой эргэх comes out as "the head spins", which makes no sense until you know it means to feel dizzy, or to be confused and overwhelmed.
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 Mongolian sentence and check what it means without breaking your reading. That is what reading in Lingo7 is built for.

In Mongolian, an idiom is called хэлц үг, and a proverb is зүйр цэцэн үг. A хэлц үг (also called өвөрмөц хэлц) is a fixed figurative phrase that has to sit inside a sentence, while a зүйр цэцэн үг is a complete folk saying that states a piece of wisdom on its own.
Idioms are non-compositional: their meaning is fixed by convention, not built from the individual words. Толгой эргэх translates literally as "the head spins", yet it means to feel dizzy, or to be confused and overwhelmed. Translate word for word and you get nonsense, so idioms have to be learned as whole units.
The fastest way is to meet them in context and reuse them, not to memorize a list. Learn a handful at a time, notice them while reading and listening, and try them in your own sentences. Reading real Mongolian with tap-to-translate, the way Lingo7 works, turns every page into idiom practice.
