Idioms for Professional and Everyday English

Read, write, and think idioms are not limited to classrooms. Many are useful in workplace conversations and everyday communication.

For example, coworkers may say on the same page when they want everyone to have the same understanding of a project. Someone may put it in writing when an agreement needs to be documented. A manager might ask a team to think outside the box when a standard solution is not working.

Expressions such as read between the lines, put two and two together, and see the big picture are also useful when discussing information, messages, and decisions.

The important point is context. Some expressions, such as put pen to paper, can sound slightly traditional even though they remain understandable and established. Others, such as think outside the box, are common in modern professional English.

Common Mistakes When Using Read Write Think Idioms

One common mistake is taking an idiom literally. For example, read between the lines does not mean physically reading the spaces between lines. It means interpreting an implied message.

Another mistake is using an idiom in the wrong situation. Put pen to paper relates to writing, while think outside the box relates to creative thinking. Replacing one with the other can make a sentence confusing.

It is also important to learn the complete expression. Say read between the lines, not simply “read between,” when you mean the idiomatic expression. Similarly, put two and two together is the established phrase for connecting information to reach a conclusion.

Finally, remember that idioms often have different levels of formality. A phrase that sounds natural in a conversation with friends may not always be appropriate in a formal academic paper.

How to Learn Read Write Think Idioms

The easiest way to learn these expressions is to connect each idiom with a realistic situation.

Start with five or six expressions rather than trying to memorize a long list at once. Write the idiom, its meaning, and one original sentence. Then look for the expression while reading articles, books, emails, or other English content.

It also helps to group idioms by function. Keep reading expressions such as read between the lines and read up on something together. Put writing expressions such as put pen to paper and put it in writing in another group. Finally, practice thinking expressions such as think outside the box, put two and two together, and think it over together.

Using an idiom in your own sentence is particularly useful because it forces you to understand the context rather than simply memorize a definition. ReadWriteThink’s idiom lesson also uses sentence writing as part of its approach to demonstrating understanding.
