ankščiau
What`s funny about it is the word does exist and it means "more cramped". But lately more and more people tend to use that in the meaning of "earlier", which is spelled "anksčiau". And the funniest thing about that is editors/proofreaders ignoring the obvious error, while editing things that need no editing at all.
See, I used to think some editors sacrifice Sense in the name of Grammar, but now I see some editors have not even learned their grammar properly...
