Imperial’s poetry is notable for its employment of foreign words and phrases. Not surprisingly, Imperial introduces many Italianisms into his poetry (most notably, the word “transumanar,” which Dante had coined in the "Paradiso"). But, in addition, the "Dezir al nacimiento de Juan II" contains lines that attempt to imitate French, Latin, English and Arabic. Another lyric contains an entire verse in what appears to be a version of Provençal (in this Imperial follows Dante, who placed Provençal verses in the mouth of the spirit of the poet Arnaut Daniel). And one of the poems about Angelina de Grecia contains a word (“cardiamo”) apparently based on Greek, and another word (“ssenguil”) which has been connected to Hungarian.
