-리라 states a resolve or a prediction in a lofty, written voice: 이것 또한 지나가리라 'this too shall pass.' None of these lines is ordinary conversation — they are proverbs, lyrics, quoted sayings and on-screen captions. It attaches after a vowel; after a consonant the same ending appears as -으리라. (The line about 1달러에 2리라 is the Turkish lira, not this ending.)
