Definition of Defence and Defense

The words “defence” and “defense” are both nouns that refer to the act of protecting something or someone from attack, harm, or criticism. They can also refer to the means used to provide such protection, or an argument or justification offered in response to an accusation.

The key difference lies in their spelling, which is determined by geographical preference.

Defense (with an “s”) is the standard spelling in American English. It is used in all contexts, whether referring to military protection, legal arguments, or personal justifications. Defence (with a “c”) is the standard spelling in British English and other Commonwealth countries such as Canada, Australia, and New Zealand. While “defense” might be understood in these regions, “defence” is the preferred and more commonly used spelling.

The function of both words is primarily as a noun. They can act as the subject of a sentence, the object of a verb, or the object of a preposition.

The context in which they are used is broad, encompassing military, legal, sports, and everyday situations.

Structural Breakdown

The structural difference between “defence” and “defense” is simply the replacement of the letter “c” with “s.” This change reflects a broader trend in American English to simplify spellings by using “s” instead of “c” in words derived from Latin. This simplification was championed by Noah Webster, whose dictionaries aimed to create a distinct American English.

Both words are derived from the Latin word defensio, which means “a defending.” The verb form, “defend,” remains consistent across both American and British English. This consistency helps to maintain a connection between the noun and verb forms, despite the spelling variation in the noun.

The suffix “-ence” (in “defence”) and “-ense” (in “defense”) are common noun suffixes in English, often indicating a state, quality, or action. The choice between “c” and “s” in these suffixes is a key marker of the difference between British and American spelling conventions.

Types and Categories of Usage

Both “defence” and “defense” can be categorized based on the context in which they are used. Here are some common categories:

Military Defence/Defense

This refers to the protection of a country or its assets from military attack. Examples include national defence strategies, missile defense systems, and border defenses.

Legal Defence/Defense

In legal contexts, this refers to the arguments and evidence presented by the accused to prove their innocence or mitigate their culpability. Examples include self-defense, defense attorney, and the defense rests.

Sports Defence/Defense

In sports, this refers to the actions taken by a team or player to prevent the opposing team from scoring. Examples include defensive players, defensive strategies, and a strong defense.

Personal Defence/Defense

This refers to the act of protecting oneself from physical harm or verbal attacks. Examples include self-defense classes, defending one’s reputation, and personal defenses.

Figurative Defence/Defense

This refers to the act of protecting an idea, principle, or belief. Examples include defending freedom of speech, defending human rights, and intellectual defense.

Usage Rules

The primary rule for using “defence” and “defense” is to adhere to the spelling conventions of the region in which you are writing. In American English, always use “defense.” In British English and other Commonwealth countries, always use “defence.”

Consistency is key. If you are writing for an international audience, you may choose to use one spelling consistently throughout your document.

However, be aware of your target audience and their expectations. If you are writing for an American audience, using “defense” will be more appropriate, and vice versa.

When quoting sources, maintain the original spelling used in the source, even if it differs from your preferred spelling. This is important for accuracy and academic integrity.

Be mindful of the spelling used in specific organizations or institutions. For example, the U.S.

Department of Defense uses the American spelling, while the UK Ministry of Defence uses the British spelling. When referring to these entities, use their official spelling.

Common Mistakes

One of the most common mistakes is using the American spelling “defense” in British English writing, or vice versa. This can make your writing appear inconsistent and unprofessional.

Another common mistake is confusing the noun forms “defence/defense” with the verb “defend.” The verb form is the same in both American and British English, so it is important to use the correct noun spelling based on the context.

A further mistake is failing to maintain consistency within a document. If you start using one spelling, stick with it throughout, unless you are quoting a source that uses a different spelling.

Here are some examples of common mistakes and their corrections:

Advanced Topics

For advanced learners, it’s important to understand that the spelling differences between British and American English extend beyond just “defence” and “defense.” Many other words follow a similar pattern, such as “offence/offense,” “pretence/pretense,” and “licence/license” (noun form). The verb form “license” remains consistent across both dialects.

Furthermore, it’s worth noting that while “defence” is the standard spelling in British English, there are exceptions. For example, in some technical or legal contexts, “defense” might be used, especially when dealing with international standards or documents that originate in the United States.

The historical context of these spelling variations is also an interesting area of study. Noah Webster’s efforts to simplify American English spellings were driven by a desire to create a distinct national identity and promote literacy.

Understanding this historical background can provide a deeper appreciation for the nuances of English spelling.
