Lifesaver

A person or thing that prevents death.

Reach for it when crediting a literal rescue or protective intervention

The flotation ring was a lifesaver when the canoe overturned.

• everyday

  rescuer

  a person directly brings someone out of danger

  not when Rescuer does not cover equipment or treatment that saves life.

• warm

  hero

  courage and personal risk deserve recognition

  not when Hero can exaggerate a routine professional intervention.

• professional

  life preserver

  flotation equipment is meant literally

  not when Life preserver is limited to water safety.

• literary

  savior

  dramatic or religious language is consciously intended

  not when Savior gives one person sweeping credit and is often too strong.

Someone or something that provides crucial help in a difficult moment.

Reach for it when offering warm informal thanks for practical assistance

• playful

  godsend

  informal relief at timely help fits the relationship

  not when Godsend carries religious coloring and can sound exaggerated.

• everyday

  great help

  plain gratitude avoids dramatic language

  not when Great help understates assistance that prevented a serious failure.

• professional

  problem-solver

  skillful resolution matters more than emotional rescue

  not when Problem-solver does not convey the urgency or gratitude of lifesaver.

• threat
• endangerment
• hindrance
