Actually, Frisk isn't the character's name, it's a word.

'''1. Toby Fox never refer to the character as 'Frisk'. 2. The pixel artist/co-roteirist of UNDERTALE [Temmie Chang] when refers to Frisk, always use lowercase, reinforcng that 'Frisk' is a word, not a name. 3. When you end the pacifist route, when you talk to Napstablook he will say your name, using quotation marks to show that it's a quote, and Frisk's name will be in lowercase, showing that when Frisk says, he says like it's a word.'''

frisk means jump

In the monsters language, fall means death, so the logic is that "jump" means live, a brazilian youtuber actually made a video 'bout this theory explaining the whole thing, even HOW Chara comes back, but it's in portuguese
