Someone who has little regard for their own personal safety. Nafod is noun that comes from the acronym “No apparent fear of death”. It is a noun, and refers to a person who has that characteristic: a dare-devil essentially. Its meaning is independent of the phrase the acronym comes from, as it specifically refers to a person instead of anything that is lacking survival instincts. The word was probably coined when someone said the phrase and realized it would work well as an acronym. It is also possible that the word apparent was added superfluously so that there was another vowel in the word and it could be pronounced like a normal English word.
