Batholith
I actually use this word occasionally in my writing. I have a love affair with mountains, so it comes up from time to time. It's also just so fun to say, it rolls off the tongue like good Highland Single Malt Scotch Whisky.
What? You don't consider Scotch that smooth? You might be drinking the wrong stuff. Anyway, let's get to the important parts:
bath·o·lith [bath-uh-lith] n. - a very large irregular-shaped mass of igneous rock, esp granite, formed from an intrusion of magma at great depth, esp one exposed after erosion of less resistant overlying rocks
Synonyms: batholite, pluton, plutonic rock
Etymology: 1903, from Ger. batholith (1892), coined by German geologist Eduard Suess (1831-1914) from Gk. bathos "depth" + -lith, from lithos "stone."
