I'm a little stuck... Click here to teach me more about this clue!

'getting' is the definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.

(Other definitions for euphemism that I've seen before include "Inoffensive expression substituted for one that may be offensive" , "Milder substitute word" , "Word used instead of something more unpleasant" , "Inoffensive term used instead of an unpleasant one" , "Mild substitute for taboo word" .)

I've seen this clue in The Telegraph.
