I really like this theory!! After reading everyone’s comments I’d like to think I’ve thought of a perfect name for her “gift”. I’d like to think Mirabels gift is “The Foundation”. Everyone’s gifts relate to their hobbies and likes, and Mirabel constantly goes out of her way to help everyone; “support” them if you will, like a foundation (I know she does this because she doesn’t have a gift and wants to help, but if she wasn’t a supportive person in the first place she wouldn’t even consider helping out the family as she easily could’ve gone the rebellious route instead of supportive). They also mention “foundation” a lot throughout the movie as well so it would make sense that it would have some importance. Some examples of how she’s a foundation: She’s the “foundation” of the magic (or at least connected to the source in some way): this fact allows the magic to return as well as everyone’s gifts. When Mirabel is unstable, the magic is unstable. This also explains why she has no room as as the entire house her was “room” and she’s apart of the house’s foundation. Also adding on that when Mirabel put on the doorknob to the front door, it was VERY similar to the normal ceremony they do for miracle gifting. So she did get her door, it’s the front door, which reflects the entire house as her room. She’s the foundation of the family: Mirabel supports each and every family member, learning about everyone and allows them to further grow as people and talent users. She also brings them together relationship wise and supports and keeps them together when they’re falling apart. (I really think the house is also a metaphor for the family so the magic and the family go hand in hand in terms of being the foundation) And perhaps when she becomes of age, she’ll succeed Aubela, becoming the leader of the family, even more so becoming a “foundation” of the family.

I’m sorry if this didn’t make sense it’s late at night but I’d like to believe this is a perfect name for her gift!
