factionalize - выдумывать;
itemize - рассматривать по пунктам;
leonize - выходить в открытый космос (образовано от фамилии космонавта А.А. Леонова);

Конверсия
Переход из одной части речи в другую, приводящий к образованию нового слова без изменения его начальной формы. Это еще один источник неологизмов в английском языке. Образованные по конверсии, они широко распространены в газетной лексике. Высокая частотность слов, образованных по конверсии - одна из отличительных черт газетного стиля. Чаще всего это глаголы, образованные от существительных, и существительные, образованные от глаголов.

Например, в паре to hit - a hit; можно наблюдать интересное развитие значения в имени существительном. В результате целого ряда переносов и переосмыслений значения a hit стало означать успех или то, что имеет успех.
