How to make a symbol by joining together 'P' and 'A'?

Question

'P' should be in the left of 'A' and of little smaller size.

Answer 1

Here I link them together with a small rule.

\documentclass{article}
\usepackage{stackengine}
\begin{document}
\[
\stackengine{0pt}{{\footnotesize P}\kern-2.5ptA}{\kern1pt\rule{3pt}{.3pt}}{O}{l}{F}{F}{L}
\]
\end{document}

Answer 2

like this ?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[frenchb]{babel}
\begin{document}

{P\scriptsize\hspace{-1em} A}

{\scriptsize P}\hspace{-1em} A

\end{document}

Answer 3

or

\documentclass{article}

\begin{document}

$\textsc{p\kern-.3emA}$

\end{document}
