Probably ‘bell-(shaped) rock or crag’ (G clag, earlier clog ‘bell’). There are several places of this name in Fife; see Elements Glossary PNF 5 under clag.
It would seem that a typographical error on OS 6 inch 1st edn has led to the existence of a ghost-name, Craig Tag, which came to be applied to a rocky hill on the west side of Ayton Hill, east of Craiglug (possibly the eponymous creag of Craiglug) (NGR NO296194, 165 m high). The OS Name Book has under Craiglug: ‘A small house one story high and in good repair, with a small garden attached. Occupied by John Smith, Forester. The property of Joseph Murray Esq. of Ayton’ (41, 7). However, on the OS 6 inch 1st edn map itself, the name appears as Craigtag, applied to the house which the OS Name Book calls Craiglug. The situation is further confused by the fact that the settlement of Craiglug had by 1977 (the date of OS Pathf. 362) been re-named Glascairn.
