I would like to create something along the lines of this:

enter image description here

I have tried, but failed miserably. I know that I can use \left[ and \right], but other than that I am completely lost. Can anybody help me out with this? Thank you in advance!

Since these are the kinds of structures you may be drawing a lot, it's really best to create some helper macros for formatting them. Here I've created a feature bundle macro that takes a comma delimited list of features and puts then in a bracketed matrix. The optional argument specifies the subscripted element for that bundle.


I've also created an uninterpretable feature macro to format features with an italic u and the feature in small caps.


Finally I've created a feature domination macro which puts two features in a domination relation:


Putting it all together we get. Personally I wouldn't use $\nu$ for little-v, but simply use $v$. I've also scaled the # sign, which in Latin Modern is quite large and ugly.

\renewcommand\#{\protect\scalebox{0.75}{\protect\raisebox{0.4ex}{\char"0023}}}% smaller \# from https://tex.stackexchange.com/q/256553/2693
} \rhd


output of code


You can obtain it with amsmath:


\usepackage{amsmath, amssymb}


\[ \nu \left[\begin{bmatrix} u\textsc{\small pers}\\ \vrule \\ u\textsc{\small part}
\end{bmatrix}_{\!\!\pi}\rhd \begin{bmatrix} u\textsc{\small pers}\\ \vrule \\ u\textsc{\small pl}
\end{bmatrix}_{\!\!\#}\right] \]%
