So, taking a quick look at the dic-tionary already gives us a quick hint, literary has several different meanings, but one of them is " having a marked style intended to create a particular emotional effect. " Therefore something such as a poem, or a love letter, both have immense literary styles, but something such as a business letter is strictly formal and contains <em>almost</em> no emotion, its simply formal, where as a poem or l.ove letter both have a lot of emotion and feeling. That makes the poem or/love letter literary, and the business letter none-literary.
Hope this helps :D
Entonces, echar un vistazo rápido al di-ccionario ya nos da una pista rápida, literario tiene varios significados diferentes, pero uno de ellos es "tener un estilo marcado destinado a crear un efecto emocional particular". Por lo tanto, algo como un poema o un Una carta de amor, ambas tienen estilos literarios inmensos, pero algo como una carta comercial es estrictamente formal y casi no contiene emoción, es simplemente formal, mientras que un poema o una carta de amor tienen mucha emoción y sentimiento. Eso hace que el poema / carta de amor sea literario y la carta comercial no literaria.
