Etymology
The verb 'delouse' is a modern 20th-century formation, created by applying the Latin-derived prefix 'de-' to the native English noun 'louse'. The prefix 'de-' carries the sense of removal or separation, directly and logically combining with 'louse' to mean "to remove lice." This compound follows a transparent pattern in English where 'de-' is attached to a noun to create a verb denoting the removal of that thing (e.g., debug, defrost). The word 'louse' itself has ancient Germanic roots, traceable back to Proto-Indo-European lūs-, and its form has remained remarkably stable in English.
