Simple Definition:

Platonic refers to a non-sexual and non-romantic relationship between two people. It is a type of friendship that emphasizes emotional connection and mutual understanding (having a strong emotional bond without being in a romantic or sexual relationship). For example, a platonic friendship could be between two close friends who enjoy spending time together and supporting each other, but do not have romantic feelings or engage in physical intimacy.

Very Simple Definition:

Platonic means having a close friendship without being boyfriend or girlfriend. It’s like having a really good friend that you care about, but you don’t have romantic feelings for them. For example, a boy and a girl who hang out and have fun together, but they don’t kiss or date. That would be a platonic relationship.
