Note 33 — Of the Streets of London. (continued 6)
Reading edition
The term rubbish is a polite corruption of the original word rubbage, which is still used by uneducated people; ish is an adjectival termination, as whitish, slavish, brutish, &c., and is used only in connection with such substantives as are derived from adjectives, as English, Scottish, &c. Whereas the affix age is strictly substantival, as sewage, garbage, wharfage, &c., and is found applied only to adjectives derived from substantives, as savage. A like polite corruption is found in the word pudding, which should be strictly pudden; the addition of the g is as gross a mistake as saying garding for garden. There is no such verb as to pud whence could come the substantival participle pudding; and the French word from which we derive our term is poudin without the g, like jardin, the root of our garden.
