This page lists subcategories for the semantic field Physical World. Category numbers are as defined by Carl Darling Buck (cf. A Dictionary of Selected Synonyms in the Principal Indo-European Languages, 1949); our field & subcategory labels are sometimes adapted from those of Buck: in our scheme they are brief but globally unique, parentheses may enclose clues (such as part of speech) to interpreting a label, and verb infinitives are introduced by 'to'.
If we have assigned, to a semantic subcategory, Proto-Indo-European lexical entries (PIE etyma) drawn from Julius Pokorny's Indogermanisches etymologisches Wörterbuch (2 vols, 1959-69), the subcategory label will be linked to a page that lists those etyma. On that page, links to PIE etyma will lead into our monolithic listing of same, and possibly to separate pages where etyma and more modern reflexes thereof (derived words, e.g. in English) are shown.
N.B. These pages are under construction; as time goes on corrections may be made, and more links from these semantic subcategories to pages of lexical entries in them, drawn from Pokorny's etyma and reflexes thereof, may be added.
