In a way that forms an acrostic, which is a type of poem or puzzle where the first letters of each line spell out a word or message.
The poem was written acrostically, with each line starting with the letters of the word 'LOVE'.
Acrostically is formed from "acrostichon" (from Greek "akrostichon", meaning the first letters of words) and the suffix "-ally" (meaning in a manner). The word refers to something done in a manner relating to the first letters of words, typically in poetry.
