Hello, The following sentence is the heading of an article to which paying subscribers to 'The Connexion' can gain access: 'How empty lock-keepers' cottages are being put to new varied use.' At first I assumed this was a spelling mistake for loch-keeper, but given the quality of this media I was surprised that they would make such a mistake, so I decided to check. In the Wordreference online dictionary, "lock" is not currently listed as an alternative spelling for "loch", so this seemed to confirm that "lock-keeper" was wrong. But in the Merriam Webster online dictionary, there is indeed an entry for "lockkeeper" (written without the hyphen), defined as "a person in charge of a lock (as on a canal)" and marked "First Known Use: 1762". However, on this same website when you search for "lock" no definition involving canals is given, and under "loch", no alternative spelling is given. I am now thoroughly confused! Is the Merriam Webster wrong too?! Can anyone help?
