158. Abbreviated Sentences

It is useful to know the kinds of word that can be left out of a sentence to save time


Abbreviation can be of both words and sentences. While abbreviated words lack some of their letters (see 130. Formal Abbreviations), abbreviated sentences lack some of their words, even ones that grammar would normally require. A well-known use of abbreviated sentences is in newspaper headlines. In the following example, three small words are missing:

(a) Queen to visit leading car manufacturer.

In most situations, the rules of English grammar would require this sentence to begin with a word like the, to include is or is going alongside to visit (because in full sentences a lone verb with to usually needs another verb with it – see 30. When to Write a Full Stop), and to add the or a before leading.

The reason for leaving out words that English grammar normally requires is to save space – newspaper headlines nearly always have to be brief. There are other places too where such abbreviation is common. Historically, telegrams – which cost a certain amount of money for every word in them – were one (I once sent my parents the message girl Emily born 22 June 01.30). In technical writing, wording on diagrams tends to be minimal. And of course notes taken in college lectures, which have to be written quickly so that none of the lecture is lost, are a source of abbreviated sentences that students are especially likely to be familiar with.

Speakers whose mother tongue is not English are likely to find abbreviated sentences problematic in both reading and writing. Readers need to recognise not just that a word is absent, but also what it is. Writers need to know which words can be left out and which cannot – for example that in (a) above to is not normally omissible. It is on these two questions that the present post offers guidelines.



There are various types of words that are not usually found in abbreviated sentences. They include the following.

1. Grammatical Omissions that can be “Understood”

Some words can be absent but “understood” without breaking any grammar rule. Obviously, they should be dropped in abbreviated sentences. In many cases, the meaning of words like this can be recognised from either the situation where they are being used or the surrounding words. Their omission is usually called “ellipsis”. The following example comes from the Guinlist post 68. How Computers Get Grammar Wrong 1:

(b) One of these housed the chapel, another (housed) a library.

The second mention of housed here is not needed to make the sentence grammatical, and if it is left out its meaning can still be understood from the first mention. For other examples of ellipsis, see 36. Words Left Out to Avoid Repetition.

It is worth noting here that not all words with an obvious meaning are grammatically optional. Consider him in the following sentence from the Guinlist post 8. Object-Dropping Errors:

(c) However bad a man may be, his relatives will not completely reject him.

Without him, its meaning is still clear but the sentence would be ungrammatical. This ungrammaticality makes obvious objects like him different from obvious words like housed in (b). However, dropping them may still be an acceptable abbreviation strategy (see #6 below).

Another kind of word that can grammatically be left understood assists the grammar of sentences more than their meaning. A very common one is that (pronounced with /Ə/ rather than /æ/), which can be either a relative pronoun or a conjunction (see 153. Conjunction Uses of “that”). Readers will be familiar with the possibility of leaving out this word when it either introduces indirect speech or represents the object of a so-called “defining” relative clause, as in this example from the Guinlist post 34. Relative Pronouns and Commas:

(d) Reforms (that) Napoleon introduced were long lasting.

Other words of this kind include in order before to and as before the object complement of a few verbs like ELECT (see 92. Complement-Showing “As”). Also worth mentioning are preposition phrases that can be paraphrased by a shorter structure, such as an adverb (see 85. Preposition Phrases and Corresponding Adverbs) or placement of their noun directly before another (see 136. Types of Description by Nouns).


2. Articles

The and a(n) are routinely absent from abbreviated sentences. The can be dropped even from people-naming adjective expressions like the poor and from “proper” nouns that normally have it, such as The West Indies or The Eiffel Tower (see 6. Adjectives with no Noun 1 and 47. Article Errors with Proper Nouns).

A possible exception might be where the article influences the meaning of the noun, as in the people (= the non-governing citizens) versus people (= human beings), went to the prison (= visited) versus went to prison (= was imprisoned), and (from the post 48. Tricky Word Contrasts 1) in the future (= predicting) versus in future (= warning).

Articles are also commonly absent from labels on diagrams. This can give a special problem when they are being referred to in an accompanying text (see 104: Naming Data Sources with “As”): in order to restore the articles correctly, the writer has to recognise which labels lack one and which do not.


3. Possessive Adjectives

Words like my, our, your and her are alternatives to the before a noun (all belong to the so-called wider class of “determiners” – see 110. Nouns without “the” or “a”). They are equally omissible:

(e) Hannibal walked (his) elephants across (the) Pyrenees.

It is obvious that the elephants here belong to Hannibal, even when his is dropped. Possessive adjectives should only be kept in abbreviated sentences when ownership is unclear.


4. The Verb BE

It is normal to drop this verb regardless of whether it has its “auxiliary” or main-verb use (see 3. Multi-Use Words). In (a) above, it is a main verb helping to express an arrangement (see 119. BE before a “to” Verb). It is an absent auxiliary in the following:

(f) “Alien” airship (is) seen by thousands.

When BE is combined with a forward-looking it at the start of a sentence (see 103. Using “it” for a Subsequent Verb), the it is normally dropped as well, like this:

(g) (It is) rare to find (an) adjective without (a) noun.

The same happens with there accompanying BE at the start of a sentence:

(h) (There are) numerous ways to learn a language.

The a is not dropped here before language because language and a language mean different things (see 23. Countable Noun Meanings 3).


5. Prepositions

If a preposition cannot be avoided by using a shorter alternative structure (see above), it might simply be omissible, like this:

(i) Ancient Egyptians wrote (on) papyrus.

Without on here, we would still probably understand that papyrus was where Ancient Egyptians wrote rather than what. In general, prepositions seem omissible if their meaning is obvious from the context. On many occasions, however, they will need to be kept. The preposition of is perhaps one of the most omissible.


6. Personal Pronouns

These comprise I, you, he, she, it and the plurals we and they. Again, there is not 100% omissibility. It seems most likely when the pronoun is repeating an earlier mention of the same idea, in either the same or an earlier sentence, like this:

(j) When hydrogen nuclei (are) fused together, (they) form helium.

(k) Caesar conquered (the) Britons. Then (he) returned (to) Rome.

Note that the above pronouns could not be left out in ordinary writing – the verbs after them need a grammatical “subject”. Some other languages allow a repeating pronoun to be left out of sentences like (j), where there is a conjunction (when). However, English only allows this after a few conjunctions, excluding when. For details, see 36. Words Left Out to Avoid Repetition.



To assist appreciation and memorization of the above points, readers are invited to put the following sentences into “note” form, using both sentence and word abbreviation. Suggested answers are given below.


1. A microscope is an instrument that magnifies small objects.

2. There is a subject that communicates more by means of short symbols than through words: it is of course Mathematics.

3. If the price of a good increases, demand for it falls (except in the case of luxury items).

4. The ancient Athenians invented drama and it possessed great importance within their democratic system.

5. It is expected that vehicles able to function without a driver will not be able to go faster than the speed limit.


Possible Answers

1. Microscope: instrum. magnifies small objects.

2. Subj. where symbols > words = maths.

3. Price increases è demand falls (except lux. items).

4. Ancient Athenians invented drama; v. important within their democracy.

5. Expected vehicles without driver can’t break speed limit.
