The problem with mediaeval lyrics is not so much the syntax, but the vocabulary, though purists get nervous breakdowns seeing the unclassical grammar. This song is a good example: the syntax is not difficult, but ever heard of laudila or lupilulat? Besides, one needs to be an ornithologist for this song. Noteworthy are also the onomatopoeic words denoting the sound the birds make. However, it is not a description of nature as such, but an invitation to dance and sing in blooming spring. The variations on this theme are almost endless in mediaeval lyrics. No wonder: winter was a time of hardship and lent was awaited eagerly.
