ORIGIN

Listicle is a portmanteau word derived from list and article.

It has been suggested that the word evokes "popsicle" (flavored and colored water frozen on a stick), emphasising  the fun but "not too nutritious" nature of the listicle (1).

A typical listicle will prominently feature a cardinal number in its title. A ranked listicle (such as Rolling Stone's "The 100 Best Albums of the Last Twenty Years") implies a qualitative judgement, conveyed by the order of the topics within the text. These are often presented in countdown order, and the "Number One" item is the last in the sequence.

Other listicles impart no such values, instead presenting the topics in no particular order, although they may be grouped by theme.

Listicles are attractive for many of the same reasons that traditional lists and checklists are – we just like to read them.
