What does "a groan" means in that sentence?We are a groan away from a watery death.
The context is the protagonist is describing his fear of living near the sea and how the sea waves sounds make him lie awake. He says that he and his family will all drown without even waking up because they're too used to sleeping through unrelenting noises. I've got a "We are too close to die by water" meaning, but I've read that "groan" is a complaining noise or something so I'm a little confused.
