Note 120 — EL CAPITÁN VENENO[4]

de punta, on end: a fine example of de used to make an adverb; we use of similarly for time (of a morning, of Sundays); Spanish uses de for adverbs of time, place, or manner. Six of the clock, of necessity, born of woman, of a truth, said of old, live of milk alone, all of a sudden, in English are of a vanishing type.
