📖 参 = consult + 照 = compare: consult a source and check against it
参 means consult or take part; 照 means compare or shine on. Together, 参照 means checking one thing against another source, like cross-checking a book for facts.
照 — 昭 (bright) phonetic + 灬 (fire radical)
照 is a semantic-phonetic compound. The bottom 灬 is a variant of 火 'fire', giving the meaning of light or illumination, while 昭 'bright' on top supplies the sound 'zhào' and reinforces the brightness sense. It originally meant to shine light on something, later extending to 'reflect', 'photograph', and 'according to'.
