To grab attention of the readers, the poets, authors and writers use techniques that let those words stay in the minds of the readers.
Explanation:
One of the techniques which is frequently used and which can be often observed in our everyday lives - news, movies, entertainment sector - is Alliteration.
The similar sound of the initial words/first letter in a line/sentence is alliteration. When there is repetition of the letter that produces the same sound while pronouncing, it creates a pattern in how we understand that sentence.
Here, 'float free' is an example of alliteration - f loat f ree - similar sound of initial words. In alliteration, the words of which first letters are repetitive and have a similarity in sound are always consonants.
