25 DIRT vs. 1228 EARTH (SOIL) vs. FILTH

[MiraAhmedovic]

When mapping Eilola-2010-210, some inconsistencies with concept 25 DIRT stood out since English "dirt" is ambiguous in meaning.

Merriam-Webster on "dirt":

• excrement: a filthy or soiling substance (such as mud, dust, or grime)
• earth: loose or packed soil or sand

We also have 1228 EARTH (SOIL) but never map English "dirt" there since we usually can't be sure which meaning is intended. That way, we're mixing potentially neutral mappings (that might be closer to 1228 EARTH (SOIL)) with mappings for "mud" or "filth" in 25 DIRT.

Should there be further splitting here? Perhaps of DIRT "Either loose or packed earth or unclean substance" (much like 25 DIRT), MUD "Wet or semi-liquid soil", and FILTH "Strongly disgusting or repulsive substances, e.g., sewage or excrement"?

@chrzyki @AnnikaTjuka would you mind giving your opinions on this?

[chrzyki]

Good observation, thanks! I'll think about that some more and reply tomorrow together with the review of #1490.

[chrzyki]

Hm, I think I'd agree that a further splitting of the concept would make sense, yes. Particularly given the current mappings (and unmapped instances of e.g. filth) we have.

[MiraAhmedovic]

Ah and since 640 MUD already exists, it would only take teasing apart FILTH from DIRT, which should be fairly sraightforward.

Sounds good to me.
