chop, divide, tear, analyze
析 centers on separating something into parts: chopping, dividing, or tearing physically, and by extension analyzing or breaking down ideas.
析 combines 木 (tree, wood) and 斤 (axe), suggesting chopping wood with an axe. This physical splitting extended to the abstract sense of analyzing or dividing.
An axe 斤 is used to chop a tree 木 into pieces. This act of splitting wood represents dividing, tearing, and analyzing.
For セキ, imagine a section of wood being chopped: section -> セキ, and the axe divides the tree.
