wondrous words

These words I came across when reading The Voyages of Dr. Dolittle:

Obstreperous- "He was such an enormous man there was no knowing what he might do if he got really obstreperous."
Definition: noisy, aggressively defiant and difficult to control

Embrocation- "... the Doctor took a large bottle of embrocation and began rubbing the sprain."
Definition: an ointment or lotion

Enteric- "They would go back to their old unsanitary ways: bad water, uncooked fish, no drainage, enteric fever, and the rest."
Definition: of the intestines

These words are from The Snowflake:

Nanoscale- "Yet self-assembly is hard to fathom because it usually involves either nanoscale objects, like the molecules in a crystal, or tremendously complex objects, like living things."
Definition: on a scale of nanometers, which is one billionth of a meter

Morphogenesis- "A flower is a biological example of morphogenesis, the spontaneous creation of form- nature using chemistry and self-assembly to generate complexity."
Definition: formation of the structure of an organism, or a part thereof

And from the books I'm currently reading, Search for the Golden Moon Bear:

Igneous- "In a great igneous spine, they run for more than six hundred miles from the northeastern corner of Cambodia up along the border of Vietnam and Laos."
Definition: formed by molten rock cooling

Lyse- "The chemicals would lyse, or burst the cells, and cause them to release their DNA."
Definition: to cause the disintegration of cells, by a chemical substance, antibody or enzyme

Montane- "If Africa is a good analogy, montane rain forest spread down, but the lowland forest became savanna in what is now the Congo Basin."
Definition: of a mountain area

and Daughters of the Sunstone:

Compunction- "I was busy," he said lamely, wondering how he had turned her away twice with no compunction.
Definition: uneasiness caused by guilt; feeling of regret

Inimical- "He should have known before he encountered the arrogant Bullens, should have known before he challenged the Arnimi force curtain, that the Arnimi would be inimical to him."
Definition: harmful, injurious; hostile or unfriendly

Insipid- "Tastes and scents grew insipid, colors dull, textures bland."

Venality- "Or did the women who governed them see that their venality was directed entirely outward?"
Definition: susceptible to bribery, corruption; using a position of trust for dishonest gain

Compendium- "She was the oldest mare of her herd and she carried the knowledge of their kind in the very tissues of her body, carried it like a compendium of redmane wisdom."
Definition: a summary of a larger work

Ostentatious- "It was a crude weapon, but she worked on it ostentatiously, hefting it, testing its balance."
Definition: showy, pretentious. That doesn't quite seem to fit here. Does anyone know another definition?

Definition: to do something without preparation or practice
