It\u2019s easy to mix up words that sound alike, such as "build" and "billed." To make sure your writing is clear, and you know which word to use, read our guide below.\n\nBuild (Construct or Develop)\nUsed as a verb, "build" typically means "construct or develop something." This might be something physical, like a model or building:\nThey like to build model aircraft.\nThe council has plans to build a new car park.\nBut it can also be more figurative, referring to a process of development:\nTaking part in team sports can build a child\u2019s confidence.\nI plan to build my business into a global empire!\nAs a noun, "build" has two main meanings:\n\n\n \tThe physical stature of someone (e.g., He had a heavy build for a sprinter)\n \tThe construction or form of something (e.g., The car's build ensures safety)\n \tA version of a piece of software (e.g., We fixed the bugs in the new build)\n\nIn these cases, then, "build" can refer to something\u2019s form or how it was developed.\n\nBilled (Charged or Promoted)\n"Billed" is the simple past tense and past participle form of the verb "bill" (i.e., prepare an invoice or statement of charges). For example:\nThe gardener billed his customers at the end of each month.\nThis means that the gardener sought payment for his services.\nOr "bill" can mean "advertise or promote someone or something," particularly on a sign or poster. For example, we could say:\nThe promoters billed the band as the festival\u2019s top act.\nLess commonly, you might see the word "billed" when reading about creatures that have a bill (i.e., a type of beak), such as a duck-billed platypus or a spoon-billed sandpiper. In this case, "billed" works as part of an adjective.\n\nSummary: Build or Billed?\nThese words sound similar and both have common uses as a verb, but they have very different meanings in practice:\n\n\n \tBuild typically means "construct or develop something."\n \tBilled is usually a past-tense form of "bill," meaning "prepare a bill" in order to seek payment for a product or service.\n\nThe key difference here is that "billed" is a variation of "bill." It also follows the standard spelling convention for past tense verbs by ending in "-ed."\nThus, if you're looking for a word related to a bill \u2013 whether a bill for payment, a sign for an event, or a beak \u2013 you will want the spelling "billed." But if you're referring to constructing or developing something, the correct spelling will be "build."\nFor more help ensuring your written work is the best it can be, try our proofreading services.
