BFFs are the Oracc glossary mechanism for word byforms of various kinds. The general mechanism allows the individual byforms to be treated under their own entries within the glossary and during lemmatization, but then be kept separate or grouped together when the glossaries are rendered.
BFFs are implemented in glossaries using the
this should be read as 'ByForm-oF', since BFFs are only given under
the entries of byforms, not of the main form. The choice of main form
depends on the language and the kind of byform.
@bff tag's syntax consists of two required and two
optional arguments. The required arguments are:
@entryin the glossary. Note that the
@bfflinkage points only from the byforms to the main form; it is an error for a word named as an OWNER in a
@bfftag to have its own
@bfftags. The link has the same form as other glossary entry links: <CF [GW] POS>. So, to link to ki aŋ, love, the OWNER argument would be: <ki aŋ [love] V/t>.
The optional arguments are:
The required order of arguments (with optional arguments indicated with a question-mark after them) is:
@bff CLASS CODE? LABEL? OWNER
The main forms in Sumerian BFFs depend on the CLASS of the BFF and are described under Classes below.
Compound byform: used for collapsed compounds of the type
mu-un-si-sa₂ instead of expected
mu-un-sa₂. With this schema, there is an entry for the
sisa which refers back to the main form
@entry sisa [set straight] V/t @bff COMP <si sa [make straight] V/t> @bases si-sa₂ @form mu-un-si-sa₂ /si-sa₂ #mu.n:~ @sense V/t set straight @end entry
The main form is the uncollapsed version of the compound.
Labels are not used for Sumerian; they are constructed from the CODE argument
Sumerian codes are used only for suppletive verbs. They are constructed of hyphen-delimited quadruples giving the following information, in the following sequence:
If the selection criterion is not relevant to the suppletion, an asterisk (*) is used. Thus, typical suppletion codes include:
