Do the other “10-12” dimensions have names? Similar to how of we name the first 3 dimensions as length, width, and height?
Or potentially a better question to get an answer I’m looking for: What do physicists/mathematicians name the other dimensions? Does the nomenclature vary depending on which multidimensional theory I am speaking of?

answers:
Jeffrey K say: No they don't have actual names. Some authors writing about 4D hypercubes made up words for up and down in the 4th direction but these are not generally accepted by everyone. Higher dimensions can be referred to with numbers or subscripts, like x1, x2, x9, x10

neb say: Don’t know where you keep getting 12 ....
In any case, the extra dimensions of string theory form a structure called a Calabi-Yau manifold, so in some sense the dimensions are interrelated. Although we generaly talk about the overall geometry of the Calabi-Yau, the dimensions are usually distinguished with indices. This is a common approach in physics since you can make concise equations that sum over indices rather than distinguish each dimension with a different nomenclature. For example, the 4 spacetime dimensions in general relativity are not given as x,y,z,t but as xᵘ where u ranges from 0 to 3. This allows the sixteen field equations of general relativity to be represented with a single equation that ranges over the 4 indices.
One last note. The extra dimensions of string theory are usually referred to as complex valued dimensions. Since a complex valued number has a real and ‘imaginary’ part, the Calabi-Yau has 3 complex valued dimensions (two degrees of freedom for each complex dimension). The mathematics really loves complex valued dimensions.

CarolOklaNola say: Time is the fourth dimension. Time is NOT a spatial dimensions. Hypothetically, you can have as many dimensions as you want that form a matrix. Satellite images can have 7 dimensions are channels or bands plus TIME, (Landsat) or 256 channels, bands, plus TIME.

billrussell42 say: no, they do not have names. except "4th dimension", "5th dimension"
etc.

ignoramus say: They are not accessible. Names are unnecessary.
