Underground underground Pretty String (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> means that <code>TERM2</code> is broader than <code>TERM1</code>, in an extremely general sense of "broader". For example, <code>TERM2</code> is, in the relevant sense, broader than <code>TERM1</code> if any of the following hold: <code>TERM2</code> is a collection that subsumes <code>TERM1</code>; <code>TERM2</code> is a collection that has <code>TERM1</code> as an instance; <code>TERM2</code> is a collection, instances of which have instances of the collection <code>TERM1</code> as parts; <code>TERM2</code> has <code>TERM1</code> as a part; This list of reasons for why <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> TERM1 TERM2)</code> could hold is not exhaustive, but it should give a good indication of how general the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rZOAVeiYGEdqAAAACs2IMmw" class="cyc_term">broaderTerm</a> relation actually is.

This is the collection of all spatial things, tangible or intangible, that can meaningfully be said to have location or position in the empirical universe. Examples of spatially-localized things include all <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> things, such as trees and ships, as well as certain <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjjo5wpEbGdrcN5Y29ycA" class="cyc_term">Intangible</a> spatial things, like the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwPzQjJwpEbGdrcN5Y29ycA" class="cyc_term">EarthsEquator</a>.
