I'll start off with some words I had to look up while reading through Elizabeth Bowen's "The Heat of the Day"
1. Crepitate
"The season was late for an outdoor concert; already leaves were drifting on to the grass stage--here and there one turned over, crepitating as though in the act of dying, and during the music some more fell."
2. Lassitude
"Such elderly people as had not been driven home by the disappearance of the sun from the last chair fearlessly exposed their years to the dusk, in a lassitude they could have shown at no other time."
3. Pertinacity
"His and her eyes met with what was already familiarity; her pertinacity and his rudeness having created a sort of bond between them and brought them to the point of a small scene."
4. Discountenance
"It could not be enough to say she was discountenanced; her eyes dropped, looking their last at those stained two of his fingers, holding the cigarette."
5. Piety
"To this spot, to which Tom had been much attached, a sort of piety made her bring any other man; she had thus the sense of living their Sundays for him."
6. Punctiliouis
"However, either the punctiliousness of a stranger or the superstition that rules any movement to do with love made the thinker wait where he was for the coming interval."
7. Apocryphal
"The autumn of 1940 was to appear, by two autumns later, apocryphal, more far away than peace."
8. Abeyance
"The frame with the regimental crest held a picture of what was at the best abeyance--at the worst, there came out of it a warning to the bottom of her heart, that no return can ever make restitution for the going away."
Oftentimes I'll have a sense of a word but will look up the exact definition for accuracy's sake. Piety for example. Anyway, use this as a springboard to document the course of your own voyage into verbosity.
Edited to make this all less anal.
I'm only stating the truth, honest!
