What does deathly mean?
"Deathly" functions both as an adjective and an adverb, and in modern English it almost always evokes the appearance or atmosphere of death rather than death itself. As an adjective it describes things that resemble death — a deathly pallor, a deathly hush, a deathly stillness — lending scenes a grim, haunted quality prized by novelists and dramatists. As an adverb it serves as an extreme intensifier, meaning "to an utter degree," though this use now survives mainly in set phrases such as "deathly pale," "deathly quiet," and "deathly afraid." The word derives from Old English, combining "death" with the suffix "-ly." Because it overlaps with "deadly," writers should note the distinction: a deadly snake can kill you, but a deathly silence merely makes it feel as if something might. Vivid, atmospheric, and unmistakably somber, "deathly" remains a powerful tool for describing fear, shock, and eerie calm.
Resembling or suggestive of death; deathlike in appearance, sound, or atmosphere.
"A deathly stillness hung over the abandoned village."
Typically applied to faces (pallor), silence, and stillness rather than to things that actually cause death.
To an extreme or utter degree; completely — used chiefly in the expressions 'deathly pale,' 'deathly quiet,' and 'deathly afraid.'
"He was deathly afraid of speaking in public."
Largely restricted to a handful of fixed collocations in contemporary usage.
J.K. Rowling chose 'Deathly Hallows' for her final Harry Potter title — and 'deathly' has been making readers shiver ever since.

Etymology of deathly
"Deathly" is formed from the Old English noun "dēath" (death) combined with the suffix "-ly" (Old English "-līc"), which originally meant "having the form or nature of." It has been used since the Middle English period, first meaning deathlike and later developing its intensifying adverbial sense. Its closest relatives are the other ancient derivatives of the same Germanic root that gave English "dead" and "death," and it corresponds to similar formations in other Germanic languages, such as German "tödlich."
How deathly is actually used
Mostly literary or dramatic in register; the adverbial use survives almost exclusively in fixed collocations such as 'deathly pale' and 'deathly afraid.' It carries a strong connotation of stillness, fear, or pallor rather than literal fatality — for actual lethality, 'deadly' is the standard choice.
Easily confused with deathly
'Deadly' means causing or capable of causing death (a deadly poison), while 'deathly' usually means resembling death or serving as an extreme intensifier, as in 'deathly pale.'
