A few days ago I got confused — a not-uncommon state for me — about the distinction between conflate and confound. Apparently my mind had conflated (merged) the two words and I was thus confounded (mixed up). Then yesterday by chance I learned a new word: treva, the obscure diacritical mark placed above a vowel to indicate that it should be pronounced independently from its predecessor, as in naïve or coöperate. A treva is also called a diaeresis — another exotic new-to-me word meaning "separation".
The treva looks identical to the pair of little dots that make a German umlaut. For my whole life I've been conflating those two symbols!

Helpful treva example: Noël. (Pronounced No-el). As HTML-entity, however, it is confounded as "&_euml;", that is an umlaut, which for "e" is nonsense. -- Bo
