The appearance of being true and real.
Early 17th century: from Latin verisimilitudo, from verisimilis ‘probable’, from veri (genitive of verus ‘true’) + similis ‘like’.
“The depth of characters gave the novel such verisimilitude.”
Pompous or extravagant in language, style, or manner, especially in a way that is intended to impress.
Late 16th century: from Latin grandiloquus, literally ‘grand-speaking’, from grandis ‘grand’ + loqui ‘speak’. The ending was altered in English by association with eloquent.
