type of bird, vine
樢 is a rare kanji with two distinct meanings that do not share an obvious conceptual center: a type of bird and a vine. Treat these as separate senses without a unifying idea.
樢 combines 木 (tree/wood) with 鳥 (bird). The exact historical origin is uncertain; it may have originally referred to a bird associated with trees or a vine-like plant, but the component relationship is not clearly established.
Picture a bird (鳥) perched in a tree (木): that bird is the type of bird 樢 refers to. For the vine meaning, imagine the tree's branches twisting like a vine around the bird.
For ト, imagine a bird in a tree making a soft 'toe' sound as it taps the branch: toe -> ト.
