Synonym discussion

Sense: verb/1

These five verbs all describe keeping something from being seen or known, but they differ in how completely and how deliberately. 'Hide' is the most general word — you can hide a toy, a feeling, or a truth, accidentally or on purpose. 'Conceal' is more formal and always implies intention: a spy conceals a microphone inside a pen. 'Disguise' means changing the appearance of something rather than just covering it: you disguise your voice on the phone, or disguise a bitter taste with sugar. 'Camouflage' comes from military language and suggests making something blend into its surroundings so it is not noticed at all: soldiers camouflage their vehicles with netting, or a person camouflages their nervousness by acting calm. 'Obscure' is weaker than the others — it means making something difficult to see or understand, not necessarily hiding it completely: fog obscured the view, or technical jargon obscured the speaker's real point. For a learner, choosing between them depends on whether the hiding is complete or partial ('obscure' vs 'hide'), accidental or deliberate ('hide' vs 'conceal'), and whether the hidden thing's appearance is actively changed ('disguise' vs 'hide').

Etymology

Medieval LatinItalianFrenchEnglish

The word 'mask' entered English in the 1500s from French 'masque', which came from Italian 'maschera' (a covering for the face). The Italian word may trace back to Medieval Latin 'masca' (meaning ghost or nightmare) or to Arabic 'maskharah' (مسخرة), meaning a clown or a mockery. The earliest English uses referred to face coverings worn at balls and in theatre. By the 1700s it was being used figuratively for anything that hides the truth, and in the 1800s it gained the cosmetic and protective meanings we use today.
