# How deal with Gothic letters, like $\mathfrak{ A,B,C,D,a,b,c,d}\dots$, when writing by hand?

In mathematics, I sometimes encounter Gothic letters, I mean the letters $\mathfrak A, \mathfrak B, \mathfrak C, \mathfrak D, \dots, \mathfrak a, \mathfrak b, \mathfrak c, \mathfrak d, \dots$. To get them in $\LaTeX$ one would use $\mathfrak{A}$ etc.

For example, in the book Model theory by Chang and Keisler, structures are denoted $\mathfrak A = (A, \dots)$, $\mathfrak B = (B, \dots)$ and so on.

I would like to know how to write this by hand.

• @fleablood: the OP knows how to typeset the symbols using LaTeX, but doesn't know how to write them with a pen. The question is definitely on topic. Aug 21, 2016 at 21:26
• @fleablood: so in your view, mathematicians spring into this world fully equipped with all they need to know to use the symbols of mathematics. I don't share your opinion. Aug 21, 2016 at 23:45

• @fleablood: did I learn how to write symbols in any maths class? Yes, I did, by watching the teacher writing. Aug 22, 2016 at 21:20

Added 20 October 2022: Uppercase Sütterlin letters that I have seen used to write mathematics at the blackboard, in some cases by Jerry Keisler, include at least $$A,B,G,M,N$$, and $$U$$.
I would probably switch to caligraphic variant for uppercase letters. For lowercase, I personally write it as filled blackboard bold (mostly for $\mathfrak{c}$ as continuum), i.e. you apply the way you write $ℝ, ℂ$ to lowercase letters and fill the space between the doubled stroke. Alternatively, you can also turn the oval-based shape into a hexagonal one.
