Compound adjectives

How they work

When a compound adjective is modifying a noun, add a hyphen.

Ex: The frequently-missing Prukalpa is not here.

When a compound adjective is not modifying a noun, don’t use a hyphen.

Ex: Prukalpa, who is frequently missing, is not here.

Why is a hyphen important?

It makes compound adjectives clearer when they appear before a noun.

We’re a fast acting team.

→ We’re an acting team that moves fast? (No!)

We’re a fast-acting team.

→ Our team acts fast. (That’s right!)

Examples

Let’s start with our favorite word, “real time”.

Our app collects data in real time.

→ Don’t need a hyphen since “real time” is an independent phrase

Collect is a real-time data collection app.

→ We need a hyphen since “real-time” is modifying the noun “app”.

Examples

Let’s start with our favorite word, “real time”.

Do other apps collect data in real time / real-time?

Examples

Let’s start with our favorite word, “real time”.

Do other apps collect data in real time?

→ Don’t need a hyphen since “real time” is an independent phrase

Examples

Let’s start with our favorite word, “real time”.

Create a real time / real-time dashboard to analyze your data.

Examples

Let’s start with our favorite word, “real time”.

Create a real-time dashboard to analyze your data.

→ We need a hyphen since “real-time” is modifying the noun “dashboard”.

Examples

Content from our website

Our network of mobile enabled / mobile-enabled sensors track the most important parameters in the world.

Examples

Content from our website

Our network of mobile-enabled sensors track the most important parameters in the world.

→ We need a hyphen since “mobile-enabled” is modifying the noun “sensors”.

Examples

Content from our website

We believe that great products are the result of human centric / human-centric design.

Examples

Content from our website

We believe that great products are the result of human-centric design.

→ We need a hyphen since “human-centric” is modifying the noun “design”.

Examples

Content from our website

We aim to solve challenges for the real world / real-world.

Examples

Content from our website

We aim to solve challenges for the real world.

→ Don’t need a hyphen since “real world” is an independent phrase.

An exception

everyday vs every day

If “every day” is used as a compound adjective, it changes to one word “everyday” (instead of adding a hyphen).

Ex: I love coming to work every day.

Ex: The everyday role of a growth marketer is to build the company.

everyday vs every day

Every day / everyday, I come to work and build cool things.

An exception

everyday vs every day

Every day, I come to work and build cool things.

→ Don’t need a hyphen since “every day” is an independent phrase.

An exception

everyday vs every day

We build products to solve every day / everyday challenges.

An exception

everyday vs every day

We build products to solve everyday challenges.

→ Need a hyphen since “everyday” modifies the noun “challenges”.

An exception

everyday vs every day

Not sure whether to use “everyday” or “every day”?

Replace the phrase with “each day”.

→ If the sentence makes sense, use “every day”. → If the sentence doesn’t make sense, use “everyday”.

Pro Tip #1

Compound adjectives with an adverb

When an adverb ending with “-ly” is the first word in your compound adjective, the hyphen is optional.

Ex: Is this slowly-moving presentation over yet? Ex: Is this slowly moving presentation over yet?

→ Both examples are fine!

Pro Tip #2

Mariner 1 exploded after 5 minutes because of a missing hyphen.

Don’t underestimate the importance of hyphens in rockets or compound adjectives.
