Tectogrammatical
lemma, t-lemma in the sequel, is one of the attributes of a tectogrammatical
node (the t_lemma attribute); it
represents the lexical content of the node.
The value of the t_lemma attribute
can be:
the basic (default) form of the word from which the node got its lexical meaning (see Section 1, “Basic form of the word”).
In case of synonymy, the t-lemma is the basic form of one of the variants (the so called representative t-lemma),
the basic form of the word from which the word represented by the node was derived (see Section 2, “T-lemma of derived expressions (representing derivation in tectogrammatical trees)”),
a so called complex t-lemma, consisting of more words (see Section 3, “Complex t-lemma”),
an “artificial” value, a so called t-lemma substitute (see Section 4, “T-lemma substitute”).
