Perhaps not, but my rudimentary understanding of Latin - learnt only in passing - has on many occasion allowed me to correctly derive and interpret words I'd never seen or heard before.

However, the rudimentary nature of my understanding has caused me on occasion to derive etymologically invalid words - such as enthnosupremacist - but fuck it, it's English - why can't I mix my etymologies?

(although in this case, I'd probably hyphenate it).

And to an extent far more versatile than anything on the English side of my understanding of language.
