Etymology
Inherited from Middle English bog (originally chiefly in Ireland and Scotland), from Irish and Scottish Gaelic bogach (“soft, boggy ground”), from Old Irish bog (“soft”), from Proto-Celtic *buggos (“soft, tender”) + Old Irish -ach, from Proto-Celtic *-ākos. The frequent use to form compounds regarding the animals and plants in such areas mimics Irish compositions such as bog-luachair (“bulrush, bogrush”). Its use for toilets is now often derived from the resemblance of latrines and outhouse cesspools to bogholes, but the noun sense appears to be a clipped form of boghouse (“outhouse, privy”), which derived (possibly via boggard) from the verb to bog, still used in Australian English. The derivation and its connection to other senses of "bog" remains uncertain, however, owing to an extreme lack of early citations due to its perceived vulgarity.
