The great grammarian Henry Fowler coined the term fused participle. The structure consists of a noun or pronoun followed by a present participle, that is, an ‑ing verb. The entire unit (noun or pronoun plus ‑ing verb) then enters the sentence and performs the function of a noun. Fowler decried the use of these structures, but they show up in the writing of good writers.
