💧 氵 water + 占 zhān = get wet; 占 lends the zhān sound
The water radical 氵 carries the moisten/soak meaning, while 占 (zhān) is the phonetic that gives the whole character its sound. To get something wet is also to 'get associated with' it.
沾 — water 氵 + divine 占 (phonetic)
沾 is a phono-semantic compound: 氵 (water) gives the meaning 'moisten, get wet,' while 占 supplies the sound zhān. Originally it referred to being dampened or soaked by water, and it later extended to figurative senses like 'be touched by' or 'gain a share of' something.
