cause keyboard_arrow_downkeyboard_arrow_up
/cause/ [k.aa1.z]
ondemand_video

A cause is something that leads to something else, the thing it leads to is called effect. That’s why you're likely to hear the phrase "cause and effect" when people are trying to analyze how things happen. The following patterns and expressions are commonly used with the noun “cause”. Note that A is the cause. B is the result.

  • The/one cause of  B is A .
  • A is one/a cause of  B.
  • Another cause of B  is A.

 

Here are example sentences:

  • One primary cause of overpopulation is the higher birth rate.
  • The leading cause of overpopulation is the higher birth rate.
  • The underlying cause of youth violence is poor social attachments from earliest childhood.
  • The ecological footprint is one primary cause of global warming.
  • The ecological footprint is one major cause of global warming.
  • Another major cause of global warming is the increasing concentrations of ozone-depleting chemicals
  • Another main cause of global warming is emissions of greenhouse gases.

 

As you can see from the examples, adjectives such as "primary", "main", "major", "leading", "underlying" are often used with the noun ‘cause’.  

The meaning of "underlying" here refers to something beneath something else. But the word carries a more subtle meaning. We use the word ‘underlying’ to describe something hidden but still important, something that is the basic or root cause of something. Therefore, when we say “A is an underlying cause of B”, it means ‘A is the root cause of B’. For example,

  • A lack of educational opportunity is an underlying cause of poverty.  

 

The word cause can also be a verb. The verb “to cause” means “to produce an effect”, like when you slice onions and it causes your eyes to water. The past tense of “cause” is “caused”, as used in the sentence “What caused you to lose your job?”  In this sentence, someone wants to know the reason the other person lost their job (which is the effect.)

The patterns often used with the verb “cause” are the following.

  • A cause(s) B
  • A cause(s) B to + Verb
  • B is caused by A

Here are examples for each of the patterns:

  • The increasing popularity of ebooks causes a decline in paper book sales.
  • The increasing popularity of ebooks causes the sales of paper book to decline.
  • The decline in paper book sales is caused by the increasing popularity of ebooks.

colony keyboard_arrow_downkeyboard_arrow_up

"Colony" can have two meanings. The first is that it is a place where a group of people with the same interest or occupation are gathered. It can also be a group of organisms of the same type living or growing together. If you have more than one colony, you change the word to colonies, with i-e-s. Let’s check out some examples:

The verb combust basically has the same meaning of the verb “burn”, and the noun ‘combustion’ basically means “burning”. We use it a lot when we talk about the burning process in car engines and power plants.

“Combustible” can be an adjective or a noun. Used as an adjective, it describes something that can be burned easily. For example:

  • The fuel is highly combustible.

Used as a noun, it refers to something that can be burned easily. For example

  • Combustibles such as coal and gasoline are easy to burn.

commonplace keyboard_arrow_downkeyboard_arrow_up
/com-mon-place/ [k.aa1.m.ah0.n.p.l.ey2.s]

Commonplace has the same meaning of ‘common’, but it carries a negative meaning of being dull and unchallenging or tired and clichéd.  For example:

  • Coffee shops in cities are commonplace.
  • Nowadays, distance-learning programs are commonplace, but some people argue that they are not as good as those attending college in person.
  • Drug use has become commonplace at rock concerts.

Commonplace can be a noun. Things that are common can be found all over the place — they're commonplace! For example:

  • We now accept cell phones and laptop computers as commonplaces of everyday life.

We often use the phrase 'It is a commonplace that' to say an idea, expression, remark, etc. that is not new or interesting. In other words, "It is a commonplace that = Everyone knows that" Look at the following example sentences:

  • It is a commonplace that we only use a small part of our brain's capacity.

  • The new lights consume less electricity.

First meaning - the use of something (such as fuel). Here are some example sentences:

  • The world's energy consumption is expected to increase considerably as a result of population growth (electricity consumption = the consumption of electricity)

One interesting phrase you can learn is "not fit for human consumption". When something is "not fit for human consumption" it means you risk getting sick, or even dying, if you eat or drink it. Here is an example:

  • This food is not fit for human consumption. [=not fit to be eaten by people]
