tacular

–tacular suffix in the forming of nouns, ‘an exciting or extravagant event’ associated with the root; in the forming of adjectives, an intensifier of the root, ‘a lot, great, large, extravagant, excessive.’ Editorial Note: Terms created with –tacular tend to be jocular one-offs, though some, like spooktacular and craptacular, appear to have more endurance. Etymological Note: From a resegmenting of spectacular, in which the syllable tacular splinters off of spec and becomes a combining form. This true segmenting of the word would ordinarily be spectacul, from the Latin spectacul-um ‘a show, spectacle, something worth observing’ and the Latin suffix –ar ‘of a kind; belonging to.’ (source: Double-Tongued Dictionary)
