Distinguish between the figurative meaning (deep involvement) and literal meaning (submersion in liquid). Context usually makes the meaning clear.
From Latin 'immersus', past participle of 'immergere' (to dip into), from 'in-' (into) + 'mergere' (to dip).
Primarily used figuratively in modern English to describe deep mental or emotional involvement. The literal meaning (to submerge in liquid) is less common but still valid.
