The Ubiquitous Nature of Abbreviations
In our fast-paced world, efficiency is key. This drive for speed and conciseness is perfectly encapsulated in the widespread use of abbreviations. Whether you're jotting down a quick note, navigating technical manuals, or even sending a text message, abbreviations are likely to be a part of your communication. But what exactly are they, and how do we use them effectively? This article delves into the fascinating world of abbreviations, exploring their formation, common types, and the rules that govern their usage, particularly within the context of clear and effective writing.

What Exactly is an Abbreviation?
At its core, an abbreviation is the shortening of a word or phrase. The term itself derives from the Latin word 'brevis,' meaning 'short.' The primary purpose of an abbreviation is to save space and time, making communication more economical. While there aren't always rigid, universal rules for creating abbreviations, certain patterns and conventions have emerged over time, making them generally recognisable and understood.
The Art of Shortening: How Do We Abbreviate?
The process of shortening words, or abbreviation, can take various forms. The presence of a period, other than at the end of a sentence, is often a tell-tale sign that an abbreviation is in play. Here are some of the most common methods:
1. Siglaison (Initialisms)
This involves taking the initial capital letters of a phrase to form an abbreviation. These are often pronounced letter by letter. A classic example is HLM (Habitation à Loyer Modéré in French, or Housing Association in English contexts).
2. Acronymy (Acronyms)
Similar to siglaison, acronymy also uses initial letters, but the resulting abbreviation is pronounced as a word. AFNOR (Association Française de Normalisation) is a good example. These are often seen in organisational names and technical fields.
3. Symbolism
Symbols are conventional signs that represent a reality, element, unit of measurement, or operation. They can consist of one or more letters. Think of currency symbols like € or measurement units like km. These are universally understood shortcuts.
4. Typographical Signalling
Certain typographical signs function similarly to symbols. The asterisk (*), for instance, is a common example, often used to denote a footnote or a missing letter.
When to Abbreviate and When Not To
While abbreviations are useful, clarity is paramount. It's generally advisable to abbreviate sparingly to avoid compromising comprehension. Abbreviations are most commonly found in:
- Notes and comments
- Bibliographical indications
- Indexes and directories
- Technical and scientific manuals
In casual communication between colleagues, abbreviations are often acceptable and denote a certain level of familiarity. However, in formal writing, especially when addressing individuals directly, the use of abbreviations needs careful consideration.
Abbreviations in Specific Contexts
Academic Degrees and Diplomas
Within the body of a formal text, terms denoting academic degrees and diplomas are typically written out in full and in lowercase. For example: "He obtained an honorary doctorate from Princeton." However, in certain documents like curricula vitae or directories, abbreviations are permissible. Diplomas such as 'certificate,' 'baccalaureate,' 'licence,' 'master's,' and 'doctorate' can be abbreviated by retaining their first letter in uppercase, followed by an abbreviation period (e.g., 'dipl.' or 'D.').
Names and Titles of People
It is generally discouraged to abbreviate names of people, titles of civility (Mr., Mrs.), or honorific titles when addressing someone directly. This also extends to the addressee's name and address on an envelope or in formal invitations. However, you may use an abbreviated title if it's followed by a name you are referring to but not directly addressing, or by a secondary title. For instance, "the trip of Mr. the Minister..."
Place Names (Odonyms and Toponyms)
As a general rule, the generic part of a street name (e.g., 'street', 'avenue') and the specific part, along with any cardinal points, should not be abbreviated. However, in addresses where space is limited, abbreviating the generic part of the street name is tolerated. The abbreviation of a cardinal point is also acceptable, provided the generic part has already been abbreviated (e.g., "10 av. Edgar Quinet, E." for "10 avenue Edgar Quinet, East"). If a cardinal point is an integral part of the specific name, it cannot be abbreviated and is often hyphenated (e.g., "10, boul. Saint-Michel"). Numbers within place names should be written out, unless they represent a date or are Roman numerals (e.g., "rue du 10 juin", "avenue Paul-VI").
Methods of Word Truncation
Several techniques are employed to shorten words:
1. Suppression of Final Letters
This involves cutting off the end of a word, often after a consonant and before a vowel. This is done when no conventional abbreviation exists. While omitting just one letter is generally not recommended for clarity, omitting two is permissible, though still not ideal. Examples include prép. (for 'préposition' or 'preposition') and janv. (for 'janvier' or 'January').

2. Suppression of Internal Letters
Sometimes, letters are removed from within a word. In these cases, the remaining letters, often after the initial letter, are sometimes placed in a raised position, like an exponent. Examples include Mme (for 'madame' or 'Mrs.') and Dr (for 'docteur' or 'Doctor').
3. Retention of Key Consonants
This method involves keeping only a few key consonants of a word. These are often fixed abbreviations where no changes are permitted. An example is qqch. (for 'quelque chose' or 'something').
Abbreviations of Compound Words and Phrases
When abbreviating compound words, phrases, or expressions, the principle is to use one element per word. Spaces and punctuation marks present in the original phrase are typically retained. However, established conventions, such as those for academic degrees, are exceptions, leading to the absence of a space after the abbreviation period. Examples include c.-à-d. (c'est-à-dire / that is to say) and P.-S. (post-scriptum / P.S.).
Truncated Words (Shortenings)
Certain short words are the result of truncating longer words, typically nouns or adjectives. These shortened forms are often associated with informal language. Truncation usually occurs through apocope (removing final syllables). The cut is often made after the first element of a scholarly compound or after the second or third syllable, especially if it ends in 'o'. Less commonly, apheresis (removing initial syllables) is used. Unlike abbreviations, truncated words do not typically take an abbreviation period. Examples include photo. (for photograph), bac (for baccalaureate), and bus (for omnibus).
Over time, some truncated words have replaced their longer counterparts, while others remain in strong competition. In such cases, the full form is often preferred in formal or technical language. Examples include métro (from 'métropolitain') and taxi (from 'taximètre').
Truncated nouns are generally invariable in gender and take a plural marker when needed. Truncated adjectives also remain invariable in gender. For number agreement, it's preferable to add the plural marker to truncated adjectives. Examples: "légumes bios" (organic vegetables), "marqueurs fluos" (fluorescent markers).
Truncation with the Addition of '-o'
A common informal method of shortening words involves adding the suffix '-o' to words truncated by apocope. Examples include alcoolo (for 'alcoolique' or 'alcoholic') and véto (for 'vétérinaire' or 'veterinarian').
Nouns and adjectives abbreviated with '-o' take a plural marker when necessary, while adverbs remain invariable. Examples: "les prolos" (proletarians), "les intellos" (intellectuals).
Accents on Capital Letters in Abbreviations
In abbreviations, just as in regular text, capital letters retain any accents, diaeresis, or cedillas present in their lowercase equivalents. For example, Éts or Éts (for Établissements / Establishments). The exception to this rule are siglaison (initialisms) for pronunciation reasons and because they have an independent status from the words they derive from (e.g., ENA - École Nationale d'Administration).
Feminine Forms of Abbreviations
It is possible to add the feminine marker to certain abbreviations if the last letter of the abbreviation is also the last letter of the full word and there is no abbreviation period. For example, Pre or Pr (for 'professeure' or 'female professor', also abbreviated as 'Prof.').

Pluralisation of Abbreviations
Most abbreviations do not take a plural marker. This applies to symbols for units of measurement (e.g., "20 m"). The same rule applies to abbreviations ending with an abbreviation period (e.g., "p. 10 à 12" for "pages 10 to 12").
When the last letter of an abbreviation is also the last letter of the full word, and there is no abbreviation period, adding an 's' is common (e.g., Mmes or Mmes for 'mesdames' or 'Mesdames', Éts or Éts for 'établissements' or 'establishments').
The plural of certain abbreviations is indicated by doubling the consonant(s) followed by an abbreviation period. An example is MM. (for 'messieurs' or 'Messieurs').
So, whether you're aiming for brevity or simply trying to understand the shorthand used around you, mastering abbreviations is a valuable skill. They are an integral part of modern communication, streamlining our language while maintaining clarity when used correctly.
Frequently Asked Questions
Q1: Do all abbreviations end with a period?
A1: Not necessarily. While many abbreviations, especially those formed by truncating the end of a word, end with a period (e.g., Dr., Jan.), acronyms (pronounced as words like NASA) and initialisms (pronounced letter by letter like UK) typically do not.
Q2: How do I know if I should abbreviate a word?
A2: Consider your audience and the context. In formal writing, it's often best to write words in full unless a widely accepted and understood abbreviation exists. In informal contexts or technical documents where space is limited, abbreviations are more common. Always prioritise clarity.
Q3: Can I create my own abbreviations?
A3: While you can create new shortenings, it's generally best to stick to established abbreviations to ensure your readers understand you. If you must create a new abbreviation, define it clearly the first time you use it.
Q4: What's the difference between an abbreviation and a contraction?
A4: An abbreviation is a shortening of a word or phrase, often indicated by a period. A contraction is the result of merging two or more words, often omitting letters, and is not usually marked by a period (e.g., don't, isn't).
Q5: How do I make an abbreviation plural?
A5: Most abbreviations do not take a plural 's'. For titles like Mr. and Mrs., the plural is indicated by doubling the letter (Mr., Mrs.) or by adding 's' if there's no period (Mmes). For many other abbreviations, the plural is implied by context or number (e.g., "several Dr.s" is incorrect; it should be "several Dr.s" or "several doctors").
