I wonder how, if at all, treacly and syrupy in figurative use differ in meaning, register, connotation, or in some other way.
The figurative senses are frequently defined synonymously in dictionaries. For instance, Merriam-Webster's Learner's Dictionary gives the figurative meaning of treacly as "something that is annoying because it is too sentimental", and that of syrupy as "disapproving : too romantic or emotional"; oxforddictionaries.com gives both meanings as "Excessively sentimental"; and the American Heritage Dictionary, 5th ed., gives both as "Cloyingly sweet or sentimental". (OED has no definition of figurative syrupy.)
An internet search yields multiple co-occurences in immediate proximity:
(E1) Either way, know this going in: This isn't your sort of generic, treacly, syrupy holiday special. (tvworthwatching.com)
(E2) I was most disheartened by Sandra Bullock’s win for The Blind Side, a treacly, syrupy overrated work ... (nhl.com)
(E3) ... almost everything about this film is positive, up until the point some people declare it treacly and syrupy sweet ... (filmjournal.com)
Are these uses entirely tautological?
