Before you choose

Infectious is a disease word first. Keep it next to a feeling noun such as laugh, smile, or enthusiasm. In writing about health or illness, choose inspiring or uplifting instead; catching and contagious are disease words too.

The word claims an effect on other people. Use it when others really did join in; enthusiasm that only one person feels is better called eager or energetic.

Spreads through the room 6

Spreading quickly to the people nearby, so that they share the feeling.

When a laugh, smile or mood spreads to the people nearby

Opposite off-putting, dampening, deflating

  • playful

    bubbly

    Fits when a casual sentence describes a cheerful, lively personality

    Not when the writing is a reference or review for an adult, where bubbly can sound lightweight and undercut their competence

  • everyday

    catching

    Fits when a casual sentence puts the word after the verb, as in her good mood was catching

    Not when it goes before a noun; a catching laugh is not idiomatic, so use contagious or infectious there

  • everyday

    contagious

    Fits when a smile, yawn, or good mood passes from person to person

    Not when the text is about health, a clinic, or an outbreak, where contagious will be read literally

  • warm

    irresistible

    Fits when a grin, a tune, or an invitation is hard not to respond to

    Not when describing a colleague or someone you are not close to; irresistible about a person can suggest romantic attraction

  • warm

    uplifting

    Fits when the feeling raises people's spirits, as with music, a story, or kind words

    Not when the mood is lively fun, such as a fit of giggles; uplifting suggests comfort or hope and can sound too earnest

  • literary

    exuberant

    Fits when someone's high spirits overflow in a way that is good to be around

    Not when you mean that others caught the feeling; exuberant describes the person's own energy, which can also tire a quiet room

When someone's enthusiasm or belief spreads through a group and gets people acting

Opposite discouraging, demoralizing, uninspiring

    Fits when someone's example makes others want to do better or try something new

    Not when the effect is a shared mood in the moment, such as laughter, with no change in what people go on to do

  • professional

    compelling

    Fits when an idea, vision, or case draws people in so they want to back it

    Not when the point is a feeling rather than an argument; compelling praises reasons, not a laugh or a mood

  • professional

    motivating

    Fits when a manager's or teammate's energy moves people to put in effort toward a goal

    Not when the effect is joy or warmth for its own sake; motivating makes it sound like a tool for output
