浸 appears in many useful compounds: 浸泡 (to soak), 浸湿 (to get wet through), 沉浸 (to be immersed/engrossed in), 浸透 (to soak through). 沉浸式 (chénjìnshì) = 'immersive' — used for language learning, VR, experiences.

氵(water) + 侵 (to encroach) minus the亻— water slowly encroaching into something. That's soaking.
Left water radical — side-form of 水 drawn as three slanted drops. As the indexing radical it carries the literal meaning: soaking, immersing, and seeping are all about water acting on something. Same radical groups 浸 with 泡 to soak, 沉 to sink, 淋 to drench, 渗 to seep.
Top-right 彐 — three-stroke shape representing a hand reaching down (a graphic remnant of 又). In 浸 it is a hand pushing something downward into the water below.
Middle-right 冖 — a horizontal canopy with a small hook. Sits between the hand above and the hand below, suggesting the surface of the water that something is being pushed under. Reinforces the 'submerging' image of 浸.
Bottom-right 又 — pictograph of a right hand. Paired with the 彐 hand above and the 冖 cover between, it pictures both hands pressing something down through the surface — the literal image of immersion that gave 浸 its meaning.
