affixed, attach, refer to, append
附 centers on adding something to an existing base: attaching, affixing, or appending. The sense of referring to something extends this idea of connecting one thing to another.
附 combines ⻖ (mound, hill) with 付, which likely contributes both sound and the idea of attaching. The mound radical may suggest something added to a hill or base.
The left side ⻖ looks like a hill, and the right side 付 suggests attaching. Picture a small hill attached to a larger mountain, like an appendix added to a document.
For フ, imagine attaching a food label to a package: food -> フ, and the label is affixed securely.
