supertype: #hadron any elementary particle that interacts strongly with other particles
supertype: #elementary_particle__fundamental_particle__fundamentalparticle__subatomicparticle a particle that is less complex than an atom; regarded as constituents of all matter
supertype: #particle a body having finite mass and internal structure but negligible dimensions
supertype: #body.natural_object an individual 3-dimensional object that has mass and that is distinguishable from other objects; "heavenly body"
supertype: #natural_object__naturalobject an object occurring naturally; not made by man
supertype: #physical_object__object a tangible and visible entity; an entity that can cast a shadow; "it was full of rackets, balls and other objects"
supertype: dl#non-agentive_physical_object__NAPO e.g., a bottle

supertype: pm#physical_entity__object spatial entity made of matter
supertype: dl#physical_endurant__PED
supertype: pm#spatial_object__spatialobject object which as a direct spatial location, e.g., physical object, spatial region or shape
supertype: sumo#object__entity_with_spatial_feature spatial object (space, location or physical object) or description medium/container (e.g., string, language, image); in a 4D ontology, an object is something whose spatiotemporal extent is thought of as dividing into spatial parts roughly parallel to the time-axis
supertype: pm#entity something that can be "involved" in a situation
supertype: pm#thing__something___T__t___3D_or_4D_thing_or_anything_else any category (type or individual) is instance of this type; any type is also a subtype of this type
supertype: sumo#physical__physical_thing an entity that has a location in space-time; locations are themselves understood to have a location in space-time; click here for more details on the identical category sowa#physical_thing
supertype: pm#thing__something___T__t___3D_or_4D_thing_or_anything_else any category (type or individual) is instance of this type; any type is also a subtype of this type
supertype: cyc#partially_tangible__partiallytangible A subcollection of cyc#SpatialThing-Localized and cyc#TemporalThing. Each instance of cyc#PartiallyTangible has a tangible (i.e. material) part and a temporal extent (i.e. it exists in time). It might or might not also have an intangible part. For example, a particular copy of a book is made of matter, has temporal extent, and also has an intangible part: the information content of the text markings on its pages.

supertype: dl#endurant__ED
supertype: pm#entity something that can be "involved" in a situation
supertype: 3D#thing an object seen from a 3D (or endurantist) perspective, i.e. where a spatial entity may have a time independent identity, as opposed for example to the 4D perspective where each spatial entity has an associated time frame; click here and here for details
supertype: pm#thing__something___T__t___3D_or_4D_thing_or_anything_else any category (type or individual) is instance of this type; any type is also a subtype of this type
supertype: dl#endurant_or_perdurant__ED_or_PD
supertype: dl#quality_or_endurant_or_perdurant__Q_or_ED_or_PD
supertype: dl#entity a category from DOLCE or generalized by a category from DOLCE
supertype: pm#individual__particular___supertype_of_1st_order_types all individuals (for concepts or relations) are implicitely or explicitely instance of that type
supertype: dl#PQ_or_PED_or_PR_or_PD
supertype: dl#quality_or_endurant_or_perdurant__Q_or_ED_or_PD
supertype: cyc#tangible Something which is not intangible, something which is physical, made of matter. It does not matter whether things are real of imaginary. Therefore we consider Mickey Mouse's car and a hippogriff as tangible things
supertype: cyc#temporal_thing The collection of all things that have temporal extent or location, i.e. things about which one might sensibly ask When? . cyc#TemporalThing thus contains many kinds of things, including events, physical objects, agreements, and abstract pieces of time. Note that cyc#TimePoint is a specialization of cyc#TemporalThing, since time points have temporal location, although they arguably lack temporal extent. Abstract things that are timeless -- such as mathematical sets, attributes, and numbers -- are of course _not_ instances of cyc#TemporalThing.
supertype: pm#thing__something___T__t___3D_or_4D_thing_or_anything_else any category (type or individual) is instance of this type; any type is also a subtype of this type
supertype: #fermion any particle that obeys Fermi-Dirac statistics and is subject to the Pauli exclusion principle
supertype: #particle a body having finite mass and internal structure but negligible dimensions
supertype: #cation a positively charged atom
supertype: #ion an electrically charged particle; an atom that has lost one or more of its electrons
supertype: #atom (physics and chemistry) the smallest component of an element having the chemical properties of the element
