That seems a pretty good definition of 'frugal' to me. To be excessively frugal would be miserly, tight-fisted or whatever.

There were a couple of definitions I did think were a bit off, e.g. 'zenith' and 'nihilism'. And one word where two answers seemed valid but I forget which.

Sometimes it gives one of several possible meanings but that's a valid choice.

In general I think it's a fun quiz - agreed with others though that the word selection brackets aren't ideal. It spends a lot of time on everyday vocabulary, then jumps straight into long words that someone made up one day as a joke.

The words I find most interesting are those that convey some subtle nuance, or describe some very specific thing - tools for old crafts, uncommon but genuinely used adjectives and the like. Very few of those appear.
