Join requires each element of its argument to be an array, and their ranks to match exactly. No rank extension is performed.

    ∾"abc"‿'d'‿"ef"  # Includes an atom
 RANK ERROR
-    ∾"abc"‿(<'d')‿"ef"  # Includes a scalar
+    ∾"abc"‿(<'d')‿"ef"  # Includes a unit
 RANK ERROR

However, Join has higher-dimensional uses as well. Given a rank-m array of rank-n arrays (requiring m≤n), it will merge arrays along their first m axes. For example, if the argument is a matrix of matrices representing a block matrix, Join will give the corresponding unblocked matrix as its result.
