Adposition

• 1. Introduction

  ›

  Adpositions are the small words that quietly hold language together. Consider the difference between "the key is under the stone" and "the key is on the stone" - a single word shifts the entire meaning. These tiny words, words like in, of, under, towards, and ago, express spatial and temporal relations, and mark the roles that nouns play in a sentence. Yet despite their invisibility in everyday speech, linguists have found that adpositions are among the most frequently occurring words in any language that uses them. In English, a frequency ranking of word forms places the prepositions of, in, for, on, and to within the first fourteen positions, nestled among words like the, and, and I. What makes adpositions so central to language? How do different languages across the world handle the job these words perform? And why do some grammarians insist that a sentence should never end with one, while others argue that rule was always a fiction borrowed from Latin?

  ›

  The word preposition comes from the Latin prae-, meaning "before", and ponere, meaning "to put". That etymology made perfect sense for Latin and Greek, where these words appear before their complements. But when linguists turned to languages like Turkish, Hungarian, Korean, and Japanese, they found that the same function was performed by words that come after the complement. For those, the term postposition was coined, drawing on the Latin post, meaning "behind" or "after". Then there are circumpositions, from the Latin circum-, meaning "around", which wrap their complements with two parts appearing on either side. The umbrella term adposition pulls all three together under the Latin prefix ad-, meaning "to". Some linguists, however, prefer to use the older, more familiar term preposition for all such words regardless of where they land in a phrase. That disagreement has never fully resolved, and both practices remain current in the field.

• 3. Position and Structure

  Northern Kurdish, also called Kurmanji, offers vivid examples of circumpositions in action. Phrases like bi...re for "with" and di...de for "in" split around their complements, placing one part before the noun and one after. English has a handful of constructions that some analysts read the same way, such as "from now on", and Dutch contributes "naar het einde toe", meaning "towards the end". Whether any given construction genuinely counts as a circumposition often depends on how the analyst reads the underlying structure; many such phrases can instead be parsed as a prepositional phrase modifying a following adverb. There is also the rare inposition, which appears between parts of a complex complement. The native Californian language Timbisha contains such forms, where a word meaning something like "from" slots between a noun and its modifier rather than at the edge of the phrase. The Latin phrase summa cum laude, meaning "with highest praise", follows the same pattern, with cum sitting between the adjective summa and the noun laude. At the furthest edge of classification, there is the interposition, used in structures like word for word or the Russian droog s droogom, meaning "one with the other", where the adposition sits between two nouns that do not themselves form a single phrase.

• 4. How Adpositions Flex and Bend

  ›

  Most adpositions are what linguists call non-inflecting, meaning they do not change their form for tense, case, or gender the way verbs and nouns can. There are striking exceptions, though. Welsh and Irish, among the Celtic languages, allow the majority of their prepositions to carry inflection for grammatical person and number. In Welsh, the preposition o, meaning "from" or "of", sprouts a full paradigm of personal forms. The first-person singular becomes ohonof, the second-person plural becomes ohonoch, and the third-person feminine singular becomes ohoni. Arabic works similarly; the preposition meaning "on" inflects differently depending on whether it attaches to a first, second, or third person. Persian has developed its own inflected prepositions: az u, meaning "from him/her", contracts to azas. Spanish and Portuguese carry a trace of this in the word conmigo, meaning "with me", a form that descends from the Latin habit of placing cum after a pronoun, as in the Latin mecum. Bororo, an indigenous language of Brazil that uses postpositions throughout, contracts the entire postposition-plus-pronoun combination into a single inflected form when the postposition modifies a pronoun rather than a full noun.

• 5. Preposition Stranding

  ›

  "On what did you sit?" is grammatically impeccable English. Most speakers, however, would say "What did you sit on?" without a second thought, and that common preference is exactly what preposition stranding names. When a word like what moves to the front of a question, it carries the preposition's meaning with it but leaves the preposition behind at the end. Stranding is common in English and appears regularly in the North Germanic languages, including Swedish. Whether it exists in German is a point of active debate among grammarians. It also turns up in certain Niger-Congo languages, including Vata and Gbadi, and in some North American varieties of French. The old prescriptive rule against ending a sentence with a preposition arose during a period when scholars were modeling English grammar on Latin. Otto Jespersen, in his Essentials of English Grammar, first published in 1933, skewered that rule with a pointed comparison: insisting a preposition must stand before its complement, he wrote, is like believing that all blackguards are black or that turkeys come from Turkey. The rule, in his view, mistook a name for a requirement.

• 6. Simple, Complex, and Frozen

  ›

  Simple adpositions are single words: on, in, for, towards. Complex adpositions are groups of words acting as a single unit: in spite of, with respect to, by dint of, next to. The line between them is not fixed. Many complex adpositions arrived through grammaticalization, a process by which separate words gradually fuse into a single unit. The English words within and beside each began as two-word combinations before merging. German spells out the uncertainty directly: current German orthographic rules permit two spellings for certain prepositions, such as anstelle or an Stelle for "instead of", and aufgrund or auf Grund for "because of". The distinction between a complex adposition and a free word combination is measured by how "frozen" the phrase has become. In English, several tests help: if the phrase contains a word that cannot appear in any other context, as in by dint of or in lieu of, it is almost certainly a complex preposition. If inserting a different article is impossible - on account of, but not on an account of - the phrase has solidified. If the noun's number cannot be changed - by virtue of, but not by virtues of - the unit is frozen. The American English preference for on the weekend, contrasted with the British preference for at the weekend, shows that even simple prepositions can divide dialects on the same question of usage.

• 7. Meaning and Metaphor

  ›

  Most common adpositions are highly polysemous: a single form carries a range of meanings that can shift considerably depending on context. A primary spatial meaning very often extends into non-spatial territory through metaphor or related processes. The English in works spatially in "in the box" and temporally in "in March" and figuratively in "in trouble". Because adpositions carry such variable weight, a single preposition in one language can require several different words in another, depending on the exact context. This asymmetry is a known source of difficulty in foreign language learning. There are also cases where the adposition carries almost no independent meaning of its own, its choice dictated by the verb or adjective it travels with: English insist on, listen to, good at. Russian similarly requires otvechat' na vopros, literally "answer on the question", for a construction where English omits any preposition at all. Spatial meanings divide further into directional and static. Directional uses generally involve motion or extent: "she ran to the fence" is telic, implying arrival at the endpoint, while "she ran towards the fence" is atelic, leaving the endpoint open. Static meanings divide into projective and non-projective: "behind the rock" likely depends on where the speaker is standing (projective), while "on the desk" does not (non-projective). German takes this a step further with case-sensitive prepositions. The preposition in takes the dative in seinem Zimmer for a static location and the accusative in sein Zimmer for directional movement into a room.

• 8. Where Adpositions End and Cases Begin

  ›

  The boundary between an adposition and a grammatical case marking is genuinely blurry, and linguists have assembled a toolkit of tests to find it. In English, the agent of a passive sentence is marked by the preposition by: "killed by a lone gunman". In Russian, the same role is marked by the instrumental case, with no separate preposition needed. Within German, the genitive case and the preposition von often exchange places: a phrase using the genitive and a phrase using von can mean the same thing, paralleling English possessive forms and the preposition of. Several formal differences help separate adpositions from case affixes in practice. Two adpositions can be joined by a conjunction and share one complement - "of and for the people" - while case affixes must each be attached individually to their noun, as in the Latin urbis et orbis. An adposition can also stand away from its noun, separated by other words, while a case marking sits directly on the noun itself. No language possesses more than a handful of distinct morphological cases, but a language can accumulate hundreds of adpositions, including complex forms. Japanese and Korean illustrate just how contested the boundary can be: their post-nominal particles are described by some linguists as case particles and by others as postpositions, and some analysts split them into two groups distinguished by their ability to combine with focus particles.
