Use "fulsome" in a sentence
"V. i.112 (241,5) [as fat and fulsome] [W: flat] _Fat_ means _dull_; so we say a _fatheaded_ fellow; _fat_ likewise means _gross_, and is sometimes used for _obscene_; and _fat_ is more congruent to _fulsome_ than _flat_."
"The word fulsome is itself becoming incomprehensible."
"Whichever approach reviewers of Suite Française took — whether they followed the ‘lost book by dead writer’ angle, or played the French guilt card — they all used the limited space left after biography to indulge in fulsome but often strangely detached praise."
