Alterous Attraction

Alterous attraction is a form of emotional attraction. Similar to queerplatonic, it describes a feeling that is not necessarily romantic in nature. The term was first introduced in approximately 2015. Since then, it has been variously used for a pull toward emotional closeness or intense feelings that may or may not have any relationship to the romantic/nonromantic binary. Since 2016, some definitions of alterous have been criticized for implying than platonic or nonromantic feelings are inherently weaker than romantic ones.

The alterous flag was made in 2016 by Tumblr user Alterous-Albatross. According to the introduction post, "The yellow stands for platonic. The gray stands for the gray area between romantic and platonic attraction. Pink represents affection. Red represents romantic."
