MARSH or BOG

But Will says that it’s even more specific than that.  That it means any sort of land that feels spongy as you walk on it but that you don’t actually sink down into. (That would be a quagmire.)  All this sparked by a topic on NPR’s Fresh Air and that got us thinking about other words we don’t use any more.  For example, fifty years ago people referred to 1901 at ”ot one” or 1903 as “ot three” but we don’t call this year ”ot six”.  Language is lost and created all at the same time.  If I told my granparents that I ”googled” on a regular basis they might question my sanity or my morals. :)  Interestingly enough, I was unable to Google “ot one”… Am I spelling this right?
