Suppletion

Suppletion is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Suppletion rather than just read about it. In short: In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognates. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular".

Key takeaways

  • Suppletion belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Suppletion to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Suppletion from memory before moving on to harder problems.

Reference excerpt

In linguistics and etymology, suppletion is traditionally understood as the use of one word as the inflected form of another word when the two words are not cognates. For those learning a language, suppletive forms will be seen as "irregular" or even "highly irregular". For example, go:went is a suppletive paradigm, because go and went are not etymologically related, whereas mouse:mice is irregular but not suppletive, since the two words come from the same Old English ancestor. The term "suppletion" implies that a gap in the paradigm was filled by a form "supplied" by a different paradigm. Instances of suppletion are overwhelmingly restricted to the most commonly used lexical items in a language.

Irregularity and suppletion An irregular paradigm is one in which the derived forms of a word cannot be deduced by simple rules from the base form. For example, someone who knows only a little English can deduce that the plural of girl is girls but cannot deduce that the plural of man is men. Language learners are often most aware of irregular verbs, but any part of speech with inflections can be irregular. For most synchronic purposes—first-language acquisition studies, psycholinguistics, language-teaching theory—it suffices to note that these forms are irregular. However, historical linguistics seeks to explain how they came to be so and distinguishes different kinds of irregularity according to their origins. Most irregular paradigms (like man:men) can be explained by phonological developments that affected one form of a word but not another (in this case, Germanic umlaut). In such cases, the historical antecedents of the current forms once constituted a regular paradigm. Historical linguistics uses the term "suppletion" to distinguish irregularities like person:people or cow:cattle that cannot be so explained because the parts of the paradigm have not evolved out of a single form. Hermann Osthoff coined the term "suppletion" in German in an 1899 study of the phenomenon in Indo-European languages. Suppletion exists in many languages around the world. These languages are from various language families: Indo-Aryan, Dravidian, Semitic, Romance, etc. For example, in Georgian, the paradigm for the verb "to come" is composed of four different roots (mi-, -val-, -vid-, and -sul-; მი-, -ვალ-, -ვიდ-, -სულ-). Similarly, in Modern Standard Arabic, the verb jāʾ ('come') usually uses the form taʿāl for its imperative, and the plural of marʾah ('woman') is nisāʾ. Some of the more archaic Indo-European languages are particularly known for suppletion. Ancient Greek, for example, has some twenty verbs with suppletive paradigms, many with three separate roots.

Example words

To go In English, the past tense of the verb go is went, which comes from the past tense of the verb wend, archaic in this sense. (The modern past tense of wend is wended.) See Go (verb). The Romance languages have a variety of suppletive forms in conjugating the verb "to go", as these first-person singular forms illustrate (second-person singular forms in imperative):

The sources of these forms, numbered in the table, are six different Latin verbs:

vādere ‘to go, proceed’, īre ‘to go’ ambitāre ‘to go around’, also the source for Spanish and Portuguese andar ‘to walk’ ambulāre ‘to walk’, or perhaps another Latin root, a Celtic root, or a Germanic root halon or hala fuī suppletive perfective of esse ‘to be’. meāre ‘to go along’. Many of the Romance languages use forms from different verbs in the present tense; for example, French has je vais ‘I go’ from vadere, but nous allons ‘we go’ from ambulare. Galician-Portuguese has a similar example: imos from ire ‘to go’ and vamos from vadere ‘we go’; the former is somewhat disused in modern Portuguese but very alive in modern Galician. Even ides, from itis second-person plural of ire, is the only form for ‘you (plural) go’ both in Galician and Portuguese (Spanish vais, from vadere). Sometimes, the conjugations differ between dialects. For instance, the Limba Sarda Comuna standard of Sardinian supported a fully regular conjugation of andare, but other dialects like Logudorese do not (see also Sardinian conjugation). In Romansh, Rumantsch Grischun substitutes present and subjunctive forms of ir with vom and giaja (both are from Latin vādere and īre, respectively) in the place of mon and mondi in Sursilvan. Similarly, the Welsh verb mynd ‘to go’ has a variety of suppletive forms such as af ‘I shall go’ and euthum ‘we went’. Irish téigh ‘to go’ also has suppletive forms: dul ‘going’ and rachaidh ‘will go’. In Estonian, the inflected forms of the verb minema ‘to go’ were originally those of a verb cognate with the Finnish lähteä ‘to leave’, except for the passive and infinitive.

Good and bad In Germanic, Romance (except Romanian), Celtic, Slavic (except Bulgarian and Macedonian), and Indo-Iranian languages, the comparative and superlative of the adjective "good" is suppletive; in many of these languages the adjective "bad" is also suppletive.

The comparison of "good" is also suppletive in Estonian: hea → parem → parim and Finnish: hyvä → parempi → paras.

Similarly to the Italian noted above, the English adverb form of "good" is the unrelated word "well", from Old English wel, cognate to wyllan "to wish".

Great and small Celtic languages:

In many Slavic languages, great and small are suppletive:

Examples in languages

Albanian In Albanian there are 14 irregular verbs divided into suppletive and non-suppletive:

Ancient Greek

Ancient Greek had a large number of suppletive verbs. A few examples, listed by principal parts:

erkhomai, eîmi/eleusomai, ēlthon, elēlutha, —, — "go, come". legō, eraō (erô) / leksō, eipon / eleksa, eirēka, eirēmai / lelegmai, elekhthēn / errhēthēn "say, speak". horaō, opsomai, eidon, heorāka / heōrāka, heōrāmai / ōmmai, ōphthēn "see". pherō, oisō, ēnegka / ēnegkon, enēnokha, enēnegmai, ēnekhthēn "carry". pōleō, apodōsomai, apedomēn, peprāka, peprāmai, eprāthēn "sell".

Worked examples

Example 1 — a first encounter with Suppletion

Start with the simplest possible case. Write down what Suppletion claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Suppletion before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Suppletion ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Suppletion

In research
Suppletion appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Suppletion in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Suppletion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Grammar, Linguistic morphology, so understanding it makes those chapters shorter.
In everyday life
Look for Suppletion outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
