Loanword from Latin. There is a very nice species of oak, the pin oak, that carries this name as its species: palustris. I FINALLY found a terrific Latin botanical translator online--for trees, at least--and just decoded Quercus palustris (Oak 'of the swamp').

Question:

'Palustris' is such a lovely-sounding word. Can anyone here break down how it comes about meaning 'swamp'? Thanks for responding. Also, are there any other common 'swamp' words that we would recognize as having sprung from 'palustris'?
