 <h1 id="couple-and-merge">Couple and Merge</h1>
 <p>Solo/Couple (<code><span class='Function'>≍</span></code>) and Merge (<code><span class='Function'>&gt;</span></code>) are functions that create a higher-rank array from lower-rank components. Each takes some number of inner arrays organized in an outer structure, and creates a single array combining all elements of those inner arrays. For example, let's couple two arrays of shape <code><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>3</span></code>:</p>

 <p>Merge is effectively a generalization of Solo and Couple, since Solo is <code><span class='Brace'>{</span><span class='Function'>&gt;</span><span class='Bracket'>⟨</span><span class='Value'>𝕩</span><span class='Bracket'>⟩</span><span class='Brace'>}</span></code> and Couple is <code><span class='Brace'>{</span><span class='Function'>&gt;</span><span class='Bracket'>⟨</span><span class='Value'>𝕨</span><span class='Separator'>,</span><span class='Value'>𝕩</span><span class='Bracket'>⟩</span><span class='Brace'>}</span></code>. Since <code><span class='Function'>≍</span></code> works on the &quot;list&quot; of arguments, it can only add one dimension, but <code><span class='Function'>&gt;</span></code> can take any number of dimensions as its input.</p>
 <h2 id="merge-and-array-theory">Merge and array theory</h2>
 <p>In all cases what these functions do is more like reinterpreting existing data than creating new information. In fact, if we ignore the shape and look at the ravels of the arrays involved in a call to Merge, we find that it just <a href="join.html">joins</a> them together. Essentially, Merge is a request to ensure that the inner arrays (which, being independent elements, could be any sort of &quot;ragged&quot; array) can fit together in an array, and then to consider them to be such an array. For this reason, Merge (or a virtual analogue) is used to combine the result cells when calling a function with Rank into a single array.</p>

 <p>The way this happens, and the constraint that all inner arrays have the same shape, is closely connected to the concept of an array, and like Table <code><span class='Modifier'>⌜</span></code>, Merge might be considered a fundamental way to build up multidimensional arrays from lists. In both cases scalars are somewhat special. They are the identity element of a function with Table, and can be produced by Merge inverse, <code><span class='Function'>&gt;</span><span class='Modifier'>⁼</span></code> <strong>on a list</strong>, which forces either the outer or inner shape to be empty (BQN chooses <code><span class='Function'>&gt;</span><span class='Modifier'>⁼</span></code> to be <code><span class='Function'>&lt;</span></code>, but only on an array, as <code><span class='Function'>&gt;</span></code> cannot produce non-arrays). Merge has another catch as well: it cannot produce arrays with a <code><span class='Number'>0</span></code> in the shape, except at the end, without some sort of prototype system.</p>

 <h2 id="coupling-scalars">Coupling scalars</h2>
 <p>A note on the topic of Solo and Couple applied to scalars. As always, one axis will be added, so that the result is a list (strangely, J's <a href="https://code.jsoftware.com/wiki/Vocabulary/commaco#dyadic">laminate</a> differs from Couple in this one case, as it will add an axis to get a shape <code><span class='Number'>2</span><span class='Ligature'>‿</span><span class='Number'>1</span></code> result). For Solo, this is interchangeable with Deshape (<code><span class='Function'>⥊</span></code>), and either primitive might be chosen for stylistic reasons. For Couple, it is equivalent to Join-to (<code><span class='Function'>∾</span></code>), but this is an irregular form of Join-to because it is the only case where Join-to adds an axis to both arguments instead of just one. Couple should be preferred in this case.</p>
 <p>The pair function, which creates a list from its arguments, can be written <code><span class='Function'>Pair</span> <span class='Gets'>←</span> <span class='Function'>≍</span><span class='Modifier2'>○</span><span class='Function'>&lt;</span></code>, while <code><span class='Function'>≍</span></code> in either valence is <code><span class='Function'>&gt;</span><span class='Modifier2'>∘</span><span class='Function'>Pair</span></code>. As an interesting consequence, <code><span class='Function'>≍</span> <span class='Gets'>←→</span> <span class='Function'>&gt;</span><span class='Modifier2'>∘</span><span class='Function'>≍</span><span class='Modifier2'>○</span><span class='Function'>&lt;</span></code>, and the same relationship holds for <code><span class='Function'>Pair</span></code>.</p>
