Pied-piping is more common in formal written English than in speech. Contrast with preposition stranding. (See Examples and Observations, below.)
The term pied-piping was introduced by linguist John R. Ross in his dissertation, "Constraints on variables in syntax" (MIT, 1967).
Examples and Observations:
- "Pied-piping [is the] construction in which a preposition is moved to the front of its clause, just before its object. Examples: To whom were you speaking?; With what did they hit it?; The shop from which I bought my gloves. As can be seen, this construction is rather formal in English; the more colloquial equivalents are Who were you speaking to?; What did they hit it with?; The shop (which) I bought my gloves from, with preposition stranding."
(R.L. Trask, Dictionary of English Grammar. Penguin, 2000)
- "In her yard she had an old catalpa tree of which the trunk and lower limbs were painted light blue."
(Saul Bellow, Henderson the Rain King. Viking, 1959)
- "We are talking about a society in which there will be no roles other than those chosen or those earned."
(V for Vendetta, 2005)
- "Identity attachment is defined here as the extent to which people consider their group membership to be an important part of how they see themselves."

- "Rehearsals, in the current ethnographic context, are defined as any musical occasions during which band members pay self-conscious attention to their manipulations of instrument bodies for the purposes of producing correct sounds."

- "The interim report is also understood to have found that a student misidentified a member of staff about whom concerns were raised."

- "Lawyers and bankers . . . are the gatekeepers of power in a society based on large corporations, most of whose shares are owned by other corporations such as pension funds, insurance companies, or unit trusts, all of which are modern legal creations."

- Pied Piping vs. Stranding
"Pied piping (i.e. preposition+relativizer) in relative prepositional constructions is [a] feature that may indicate formal speech. Stranding of the preposition is usually looked upon as less formal where variation between the two constructions is possible (see Johannsson and Geisler 1998). . . .
"A good representative of a male letter writer who uses pied piping constructions is Lord Byron. In all 18 of his prepositional constructions, piped piping occurs. In 13 of these, there is a choice between pied piping and stranding.
I have gotten a very pretty Cambrian girl there of whom I grew foolishly fond, [...] There is the whole history of circumstances to which you may have possibly heard some allusion [...]Stranding, on the other hand, is more frequently used by female letter writers (37%) than by male letter writers (15%). In example (39), which is from Jane Austen's letters, it is possible to see variation between pied piping and stranding.
(Letters, George Byron, 1800-1830, p.II, 155)

[p. 62] [...] Oh! dear Fanny, your mistake has been one that thousands of women fall into.

- One of the surprising mysteries of grammar is the existence of Pied-Piping, the fact that the grammar machine may move more than is initially needed:
4. (a) a picture of whom did he see. . . Note that, in principle, the same distinction, less contrastive intuitively, is found in cases like:
4. (b) who did he see a picture of
4. (c) who did you talk to(Tom Roeper, "Multiple Grammars, Feature Attraction, Pied-Piping, and the Question: Is Agr Inside TP?" in (In)vulnerable Domains in Multilingualism, ed. by Natascha Müller. John Benjamins, 2003)
4. (d) to whom did you talk.
