Through this background information, we strive to make words more vivid and easier to understand, and help you remember their meanings in real life.
Note 2: LexiTalk designs the learning flow around the linguistics principle of “Comprehensible Input.” When learners encounter material that is slightly above their level but still understandable from context, the brain naturally absorbs the language. That’s why we keep every word inside authentic contexts, using examples and associations to help you understand it and use it flexibly.

Start by reaching into your pocket and move your fingers to the coins or card. The weight shifts as a price tag catches your eye, and you adjust your grip on the wallet. When you decide to buy, the number in your mind becomes real, a mix of need and choice. That moment of choosing what to spend is the living sense of cost.
Real Context
Cost is the amount of money required to obtain something, but it also captures the effort, time, and trade-offs involved. In everyday speech we talk about the cost of groceries, but we also speak of the cost of waiting for a service or the cost of making a difficult decision. As a verb, cost means to require payment or to entail a certain expenditure. Learners should distinguish between cost as a noun (the price) and verb (to demand money or resources). Common phrases include "high cost," "costs a lot," and "at no cost" (meaning free). Thinking about opportunity cost helps explain why choices matter beyond their price.
Usage Reminders
- Distinguish cost (noun) from cost (verb).
- Ask whether you mean the price or the burden.
- Note collocations: cost of, costs a lot, at no cost.
- Compare cost with price and with expense.
- Think about opportunity cost when making choices.
Common Misconceptions
- Cost = price; they are interchangeable
- Cost only refers to money, not time or effort
- Costs always decrease over time
- Cost applies only to goods, not services
- The verb cost and the noun costs are the same form
