Are lexicographers good spellers?
Most lexicographers are good spellers, if only owing to lots of practice. Lexicographers take the same view of language as other linguists. They know that language use varies widely in space and time, and they spend much of their time charting its changes through history. They are therefore not shocked or surprised to encounter variation in spelling. At the same time, they recognize that there is a standard set of conventional spelling rules to which we all mostly conform, and which assist good communication.
