You’re pretty well-grounded
Posted: January 5, 2016 Filed under: WORD BLENDS | Tags: expressions, grounded, humor, language, malaphor, malaphors, well-rounded, words 2 CommentsThis a nice malaphor word blend of “grounded” (sensible) and “well-rounded” (having desirably varied abilities). Perhaps the speaker meant to meld the two meanings into a new word, but probably just mixed rounded and grounded, which is easy to do. A big thanks to my cousins from Down Under, Manny Manatakis for uttering this gem and Gemma Martinez for hearing it and passing it on.
Malaphors 
Can’t a person be well- grounded in a subject such as math or politics or history or a foreign language? I understand that it depends on the context, just saying that this is a malaphor where context may be important..

perhaps, but I have always understood the phrase to be grounded in something, not well-grounded.
