How does "bog obvious" fit in to the definitions given? Simply an expletive deriving from the meaning of "toilet" or "bugger"? "Bog standard" is another phrase that can be found in use. --184.108.40.206 06:29, 31 May 2008 (UTC)
- Might be connected to bog standard, box-standard; bog ordinary, box-ordinary rather than to bog itself. DCDuring TALK 10:32, 31 May 2008 (UTC)
Suggest that BOG is borrowed from the Celtic dialects, rather than being handed down through the millennia, else the 'B' or 'G' would have been subsequently hardened. By -ACH and -AKOS, is meant, Old Irish BOGACH and Proto-Celtic *BOGAKOS, respectively - totally logical.
 means 'Absolutely not;  means 'Exceedingly unlikely';  means 'Very dubious';  means 'Questionable';  means 'Possible';  means 'Probable';  means 'Likely';  means 'Most Likely' or *Unattested;  means 'Attested';  means 'Obvious' - only used for close matches within the same language or dialect, at linkable periods.
Worth noting that Collins and Oxford Dictionaries Online connect it to the Celtic-derived terms but the OED itself and Merriam-Webster treat it as a separate and uncertain etymology. — LlywelynII 00:59, 2 April 2016 (UTC)
