Questions & Answers about Nemo est qui tonitrum et fulgur non timeat.
Because nemo means no one / nobody, and Latin treats it as grammatically singular.
So:
- nemo est = there is no one
- not nemo sunt
Even though it refers to all people in a general sense, the grammar is singular, just like English no one is, not no one are.
This is a very common Latin pattern:
- nemo est qui... = there is no one who...
Latin often uses est plus a relative clause to make a general statement about a type of person.
So this sentence is built as:
- nemo est = there is no one
- qui ... timeat = who would / who does fear
Together: There is no one who does not fear thunder and lightning, i.e. everyone fears thunder and lightning.
Qui is the relative pronoun, meaning who here.
It refers back to nemo:
- nemo = no one
- qui = who
