The word "depreciate" means "to lessen the price or value of". This is
an accounting jargon term referring to the process by which assets
lose value over time. It is pronounced 'Dee Pree Shee Ate".
The word "deprecate" means "to express disapproval of" or "to urge reasons
against; protest against". This is a programming jargon term
describing the process by which APIs become less favorable over time.
It is pronounced "Deh Preh Kayt".
These words, while they have similar meanings, are not synonyms.
Please do not confuse them, especially when using their jargon senses.
It sounds like nails on a chalkboard to me, having worked on accounting
software. I would like to be able to use phrases like "a deprecated
depreciation function" without eliciting bewilderment.
Both Java and Python consistently use "@deprecated", and
"DeprecationWarning". English usage of these terms may be shifting,
but "DepreciationWarning" or "@depreciated" will still get you runtime or
compiler errors, so please stick to "deprecate" consistently while talking
about code.
Thank you.
