You’d think at first glance, proscriptive grammar would be hard, ’cause that involves telling right from wrong, and such judgements are not simple.
On the other hand, descriptive linguistics seems simple, since all that involves is recording what people are saying and how it hangs together…. Except that everyone time someone opens their mouth, that’s more work.
And I wouldn’t want it any other way. ^_^
