I majored in geology and generally hear it as reg'-o-lith. With a short e.  Flight Risk (talk) 19:39, 17 November 2017 (UTC)
thread_title: Pronunciation?

message: Does regolith refer to any loose heterogeneous matter lying atop the bedrock, hence including soil, sand, peat, etc?  Or is it loose rocky material only?  --Andrew 06:37, Dec 14, 2004 (UTC)
It is the totality of the weathered part of the rock, including the soil, subsoil, saprolite zone and the weathered rock which is in-situ but which is being weathered from fresh silicate minerals to clay minerals. Rolinator 07:42, 10 March 2006 (UTC)
thread_title:  Generality of definition? 

message: Why not just call it dust or gravel and leave it at that? Why go about renaming it as "regolith"? You noticed rocks, dirt, dust, and gravel on Earth also belonhing in the category, so what's the problem with calling the pulverized rocks on the moon something similar? 204.52.215.107 02:20, 17 October 2007 (UTC)
replies: text: Not to mention that regolith has a specific meaning that isn't encompassed by "dust" and "gravel". They don't mean the same thing, so they're not interchangeable. Bryan Derksen (talk) 08:57, 18 April 2008 (UTC)

message: As my subject suggests; this is a quote. When I see a quote, I like to know where it came from.  —Preceding unsigned comment added by 70.137.159.123 (talk) 04:25, 30 November 2007 (UTC)

message: The caption on this image indicates, "Pebbles on Titan's surface, imaged from a height of about 85 cm by the Huygens spacecraft."
I'm going to venture a guess that the spacecraft was more than 85 cm from the surface.  Anyone able to confirm this number?  —Preceding unsigned comment added by 74.212.144.201 (talk) 18:19, 29 July 2009 (UTC)

message: Normally, the spelling would be rhegolith, with a letter ‘h’ following initial ‘r’ for a Greek word beginning with rho.  The spelling is in fact misleading, suggesting a “ruling rock.” hgwb (talk) 06:29, 11 July 2010 (UTC)
thread_title:  Spelling 

message: The German Wikipedia has a different etymology for regolith. It says: ῥῆγμα, regma = Bruch und λἰθος, lithos = Stein (Bruch meaning fracture). This explanation makes as much sense to me as rhegos (ῥῆγος), "blanket"... from this page (regolith is broken, and it covers the rock below). I don't speak any Greek. Which one is correct? --史慧开 (talk) 08:52, 26 June 2011 (UTC)
replies: text: I imagine it's the latter, though don't have a citation. Based on past experience of scientific use of Greek, the former would have been rendered as "regmalith". This would need a primary cite though - probably back in some horrible grey literature. DanHobley (talk) 10:26, 11 December 2017 (UTC)
replies: text: OK, the geomorphology bible (Anderson & Anderson, 2010) has the derivation as explicitly the "blanket" one (p. 162). So the English article is correct, unless someone can find a reference to the contrary. DanHobley (talk) 10:29, 11 December 2017 (UTC)
