You know, sometimes a word just feels right, doesn't it? And other times, you pause, tilt your head, and wonder, 'Is that really a thing?' That's precisely the feeling I get when I hear or see the word 'costed.' It sounds plausible, almost like it should be a word, but is it a proper one?
Let's dive in, shall we? When we look at 'proper,' the Cambridge Dictionary offers a few helpful definitions. It can mean 'right or suitable for a particular situation or purpose.' Think of needing 'proper walking boots' for a long hike, or having 'proper equipment' for a job. It also touches on being 'socially acceptable' or even 'complete' in an informal, British sense – like getting into a 'proper mess.'
Now, where does 'costed' fit into this? The word 'cost' itself is a verb, meaning to have a price of, or to require the payment of. We say something costs money, or a project cost a lot. The past tense is 'cost,' and the past participle is also 'cost.' So, grammatically speaking, if you're talking about something that has already been priced out, you'd say it 'was costed' or 'has been costed.'
This is where 'costed' as a past participle, derived from 'cost,' seems to align with the 'proper' definition of being 'right or suitable for a particular situation.' When a project has undergone a costing process, it has been 'costed.' It's not about the price itself, but the action of determining that price. For instance, 'The new proposal has been thoroughly costed by the finance department.' Here, 'costed' functions as a past participle, describing the state of the proposal after the costing process.
However, the reference material also points out that sometimes, instead of the adverb 'properly,' the adverb 'proper' is used, especially in British English, though it's noted as 'not standard.' This suggests that language can be a bit fluid, and what's considered 'proper' can sometimes shift or have regional variations. 'She talked proper' is an example given, meaning she spoke correctly or articulately.
So, back to 'costed.' Is it a proper word? Yes, in the sense that it's a valid past participle of the verb 'to cost.' It's used to describe the action of having been priced or evaluated financially. It fits the 'suitable for a particular situation' definition because it accurately describes the state of something that has undergone a costing exercise. While you might not find it in every single dictionary entry as a standalone word with its own definition, its grammatical function as a past participle makes it perfectly acceptable in contexts where you're referring to the process of costing.
Think of it this way: we use 'tested' to mean something has undergone testing, 'painted' for something that has been painted, and 'costed' for something that has been costed. It follows the same linguistic pattern. So, the next time you encounter 'costed,' you can be confident that, in the right context, it's not just a word, but a proper one.
