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 isogonic line IsogonicLine An <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rmhpNoE--EdqAAAACs6hO_g" class="cyc_term">IsogonicLine</a> is an intangible curve on the Earth's surface (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwCl_n5wpEbGdrcN5Y29ycA" class="cyc_term">EarthsTopographicSurface</a>) connecting points of constant magnetic declination. GeographicalLine-Intangible intangible geographical line A specialization of both <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvc-YsJwpEbGdrcN5Y29ycA" class="cyc_term">GeographicalThing_Intangible</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvpeTbpwpEbGdrcN5Y29ycA" class="cyc_term">LineSegment</a> (qq.v.). This is the collection of one-dimensional intangible geographical lines, fixed-location or otherwise. Its specializations include <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwVGrQ5wpEbGdrcN5Y29ycA" class="cyc_term">LatitudeLine</a>, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWRzmZwpEbGdrcN5Y29ycA" class="cyc_term">LineOfMilitaryForces</a>, and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkLfZwpEbGdrcN5Y29ycA" class="cyc_term">GeopoliticalBorder</a>. isogonic line IsogonicLine An <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rmhpNoE--EdqAAAACs6hO_g" class="cyc_term">IsogonicLine</a> is an intangible curve on the Earth's surface (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwCl_n5wpEbGdrcN5Y29ycA" class="cyc_term">EarthsTopographicSurface</a>) connecting points of constant magnetic declination. type of temporally stuff-like thing A specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVir35wpEbGdrcN5Y29ycA" class="cyc_term">StuffType</a> (q.v.) whose instances are all and only those collections that are temporally stuff-like. A collection <code>COL</code> is temporally stuff-like just in case every purely temporal part (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a>) of an instance of <code>COL</code> is itself an instance of <code>COL</code>, unless it is a temporal part of a temporal granule of <code>COL</code> (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a>). More precisely, for a collection <code>COL</code> to be an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a> it is both a necessary and sufficient condition that for any <code>OBJ1</code> and <code>OBJ2</code> (with <code>OBJ2</code> at or above <code>COL</code>'s temporal granularity level), if <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ1 COL)</code> and <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> OBJ1 OBJ2)</code>, then <code>(<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViBBJwpEbGdrcN5Y29ycA" class="cyc_term">isa</a> OBJ2 COL)</code>. Consider <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. Take an arbitrary instance <code>WALK</code> of this collection (say Miss America 2000's victory walk down the runway and back); and then take an arbitrary time-slice <code>SUBWALK</code> of <code>WALK</code> that subsumes at least one instance of (the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaJJwpEbGdrcN5Y29ycA" class="cyc_term">granuleOfTemporalStuff</a> for <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>) <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViYBpwpEbGdrcN5Y29ycA" class="cyc_term">TakingAStep</a> (say her trip back from the end of the runway). <code>SUBWALK</code> is itself an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a>. So <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi0gpwpEbGdrcN5Y29ycA" class="cyc_term">WalkingOnTwoLegs</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>. See <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViq35wpEbGdrcN5Y29ycA" class="cyc_term">TemporalObjectType</a> for the disjoint notion of being temporally object-like. TemporalStuffType
