«Lo inefable» is one of Delmira Agustini's most intense sonnets. The speaker says she dies «strangely»: she is killed not by life or death or love, but by a silent thought that grows inside her like a wound, something that has no word and so cannot be brought to birth.
The closing image is fierce: it would be «divine» to burst and die of that thought, like someone trying to hold in their hands «a star» that burns and will not fit. Agustini was the great female voice of modernismo, and here she takes her language — sensual, exalted — to name precisely what will not be named: the inner life that overflows the body.
The verse is kept in Spanish. Translating it in passing would replace the work with a paraphrase of it.
