Cost or Costed – Which Is the Correct Past Tense?

Marcus Froland

English can be tricky, especially when it comes to choosing the right past tense form of a verb. You’ve probably come across this dilemma before. Take the word “cost,” for example. It looks straightforward until you have to write about something that happened in the past. Then, suddenly, you’re stuck trying to figure out if “cost” turns into “costed.”

Grammar rules often seem like they require a secret code to understand them fully, but don’t worry. We’re about to get into the nitty-gritty of how simple words can trick even the most confident English speakers. And I promise, by the end of this article, you’ll look at these verbs in a whole new light — ready to use them with ease.

The correct past tense of cost depends on the context, but in most cases, “cost” remains unchanged. For actions in the past that refer to the price of something, we say it “cost” a certain amount. Example: “The book cost $20 last year.” However, when referring to someone calculating expenses or needing an estimation in the past, “costed” is sometimes used in British English, though it’s rare and considered non-standard by many. In American English and most formal writing, we stick with “cost” for all past tense uses. For example: “We need to know how much it cost to produce these items.”

Understanding Irregular Verbs: A Look into ‘Cost’

When it comes to English grammar rules, irregular verbs play a vital role in determining the proper verb usage in different contexts. To gain a better understanding of the cost past tense form, it’s crucial to first explore the concept of irregular verbs.

The Concept of Irregular Verbs in English Language

Irregular verbs in the English language deviate from the common -ed ending that regular verbs adopt in the simple past tense and the past participle forms. Unlike regular verbs, which involve adding -ed or -d to the base form to create the past tense, irregular verbs do not follow a consistent pattern and can vary in their conjugation.

Take, for instance, the verb “run.” The simple past tense of “run” is “ran,” while the past participle is “run.” Similarly, the verb “sing” changes to “sang” in the simple past tense, and “sung” as a past participle. Thus, irregular verbs are unique in their conjugation and must be memorized individually.

Is ‘Cost’ An Irregular Verb?

Yes, ‘cost’ is indeed considered an irregular verb in American English. The verb’s uninflected form in the past tense implies that there is no change from its present form. Therefore, the simple past tense and the past participle for ‘cost’ both remain unchanged from the base form:

  1. Present tense: cost
  2. Simple past tense: cost
  3. Past participle: cost

This classification is the reason why ‘cost’ does not receive the typical -ed ending that many past tense and past participle verbs do.

Common Misconceptions About Past Tense Verbs

“All past tense verbs must end with -ed or -d.”

While the above statement holds true for many regular verbs, it is not the case for irregular verbs, like ‘cost’. It’s important to remember that there is no change in the spelling of ‘cost’ when transitioning from present to past tense. This deviation from the common misconception makes it an irregular verb and adds to the nuances of English grammar.

Understanding the past tense of ‘cost’ and the underlying classifications of irregular verbs is crucial for using the English language accurately. This knowledge can help clear up any misconceptions surrounding past tense conjugation and improve overall language skills.

The Historical Usage Trends of ‘Cost’ and ‘Costed’

In both American and British English, the simple past tense of the verb ‘cost’ has traditionally been favored over ‘costed.’ Although ‘costed’ is not incorrect, it has seen far less frequent use and is more commonly encountered in Canadian English and other English varieties outside North America.

“The price of the car cost me $20,000 five years ago.”

Throughout the years, usage trends cost vs costed have varied based on region and context. In American and British English, ‘cost’ became established as the primary past tense form due to the simplicity it offers in maintaining an unchanged verb. However, in other English-speaking countries, such as Canada, ‘costed’ saw increased usage, especially in cases where the verb served in the estimation of financial requirements or pricing.

Historically, many famous literary works have also utilized ‘cost’ as the past tense form, contributing to its popularization over time. For example, in Charles Dickens’ A Tale of Two Cities, the verb ‘cost’ is employed to evoke the past tense through various instances:

“It had cost him so much.”

“It cost him something to say this.”

Understanding the historical verb usage of ‘cost’ and ‘costed’ is crucial for readers and writers alike, as it showcases how a word’s usage shifts over time, depending on regional preferences and contexts. By examining these historical trends and acknowledging the linguistic nuances, it becomes easier to choose the appropriate past tense form for your intended audience.

Examining the Variations: American vs. British English

In the world of English language variations, several differences set apart American and British English. One such difference is the usage of the past tense for certain verbs. This section will explore these distinctions, focusing on the verbs ‘cost’ and ‘costed’ to offer insight and understanding.

‘Cost’ in American English: Simplifying the Past Tense

When it comes to the past tense in American English, ‘cost’ is the primary choice for the past tense and past participle of the verb. This simplified approach remains consistent across various contexts, solidifying it as a staple in American vocabulary. This irregular verb retains the same form as the present tense, reflective of its status as an unchanged verb. For example:

It cost me $50 to replace my broken phone screen.

‘Costed’ Across the English Varieties

While ‘cost’ dominates American English past tense usage, other English-speaking countries outside of the United States, such as Canada, have adopted ‘costed’ in certain contexts. Specifically, ‘costed’ finds relevancy when employed in scenarios depicting the process of estimating financial requirements or pricing:

The event organizers costed the entire festival at approximately $200,000.

Beyond the Canadian context, some British English speakers also use ‘costed’, primarily in financial circles. However, the general preference still lies with ‘cost’, even in the United Kingdom.

Recognizing and understanding these nuanced differences between American and other English varieties can enhance your communication abilities in various settings, emphasizing the importance of catering to your audience.

When to Use ‘Cost’ and When to Use ‘Costed’

Understanding the nuances of when to use ‘cost’ and when to use ‘costed’ is essential for maintaining accuracy and clarity in your writing. While these terms may seem interchangeable, specific contexts dictate their appropriate usage to convey your intended meaning effectively.

Cost is widely used as the past tense of the verb ‘cost’ in American and British English and when it functions as a linking verb. For example:

Last year, the concert tickets cost $50 each.

However, costed might be more appropriate when catering to Canadian audiences or when referring to an action verb to estimate the cost of something. For instance:

Our marketing department costed the new advertising campaign at $15,000.

To navigate the fine line between these two options, consider the following guidelines:

  1. Use cost when discussing the value or price of an item or service (linking verb).
  2. Use costed when referring to the act of estimating the cost or expenses related to a project (action verb).
  3. Know your audience: stick to ‘cost’ for American and British English, but consider ‘costed’ for Canadian English and other English varieties.

By using ‘cost’ and ‘costed’ correctly, you’ll ensure that your writing remains accurate and easily understood by your readers, regardless of their regional English variety.

In each of the above statements, notice how the verb “cost” establishes the price of the item or service being discussed. Additionally, “cost” remains consistent when indicating the price of something across various contexts, resulting in an unaltered use of the verb.

Finally, take a look at the following example that employs “cost” within the context of real estate:
