# Letter-like symbols

Letter-like symbols such as \infty, \partial, and \hbar.

https://texform.dev/latex/topics/letter-like

This topic has 61 symbols from the ams, base, and physics packages. Symbols are single characters and are not render-tested, so they carry no support level. Entries are ordered by how often they appear in corpus formulas.

Packages: ams (30), base (28), physics (3).
