A new euphemism for "development": "advancement".

[KamaAina]

"development" itself is a euphemism for the dreaded "fundraising".

[Chan790]

1. Not actually new.

"Advancement" has been around as long as "development"...they don't exactly overlap (development is purely about raising funds while advancement generally is understood to also involve indirect financial or resource gains for an institution) and both are used in preference to "fundraising" to denote that development/advancement is generally understood to be a professional systematic approach to raising funds where fundraising can be anything and is often non-systematic and non-professional.

A development professional uses tools such as gala fundraising, capital campaigns, grantwriting, estate-planning/bequeathment, donor relationship management, and targeted major-gift solicitations.

Fundraising, as often as not, is things like bell-ringing and candy-bar sales.

(This is something that gets my goat if you can't tell. I spent years of training and education to become a development professional and prefer to not be conflated with Little Leaguers selling candy bars door-to-door.)
