Glossary¶

Sanskrit¶

Generally, these are used to describe concepts from the grammatical tradition.

aṅga: _
anubandha: See it.
abhyāsa: If a term is doubled, abhyāsa refers to the first part.
abhyasta: If a term is doubled, abhyasta refers to the two parts together.
ātmanepada: The last 9 tiṅ suffixes.
ārdhadhātuka: Refers to certain kinds of verb suffixes.
Aṣṭādhyāyī
Ashtadhyayi: A list of rules. It takes some input and produces one or more valid Sanskrit expressions.
it: An indicatory letter.
upadeśa: A term stated with its indicatory letters (it).
guṇa: An operation that strengthens a vowel to the “medium” level (a, e, o, but ṛ and ṝ become ar). Also refers to the result of this operation.
vṛddhi: An operation that strengthens a vowel to the “strong” level (ā, ai, au, but ṛ and ṝ become ār). Also refers to the result of this operation.
tiṅ: Refers to one of the 18 basic verb suffixes: 9 in parasmaipada and 9 in ātmanepada.
dhātu: A verb root.
Dhātupāṭha
Dhatupatha: A list of verb roots. These roots are used as input to the Ashtadhyayi.
parasmaipada: The first 9 tiṅ suffixes.
pratyaya: A suffix.
vibhakti: A triplet of noun/verb endings. Also, an ending within that triplet.
saṃjñā: A technical name that is assigned to a group of terms. For example, pratyaya is a saṃjñā for the set of all suffixes.
sārvadhātuka: Refers to certain kinds of verb suffixes. Generally, tiṅ and śit suffixes receive this saṃjñā.
sthānī: In a substitution, the term where the substitution occurs.

English¶

Generally, these are used to describe concepts in the program.

base filter: A filter defined in an inherit() decorator. It is “and”-ed with all of the rule tuples created by the decorated function.
center context: The term that undergoes substitution. In a saṃjñā rule: the term that receives the saṃjñā.
filter: A callable object that is used to test for a certain context. For details, see the Filter class.
left context: The term(s) that appear immediately before the center context. If no center context is defined: the term(s) after which something is inserted.
metarule: A rule that defines part of the metalanguage of the Ashtadhyayi. Some are explicitly stated, but many are implicit.
operator: A callable object that is used to apply an operation to a state. For details, see the Operator class.
ordinary rule: A rule that takes some input and produces some output(s). In this documentation, such rules are usually just called “rules.”
right context: The term(s) that appear immediately after the center context. If no center context is defined: the term(s) before which something is inserted.
rule tuple: A special shorthand for specifying rules of the Ashtadhyayi. This must be expanded into a full Rule definition before it can be used.

it tags¶

kit: Prevents guṇa and vṛddhi. If a replacement is marked with k, it is added to the end of the sthānī.
ṅit: Prevents guṇa and vṛddhi. If a replacement is marked with ṅ, it replaces the last letter of the sthānī.
ñit: Causes vṛddhi for certain vowels.
ṭit: If a replacement is marked with ṭ, it is added to the beginning of the sthānī. If a lakāra is marked with ṭ, then it undergoes some basic rules, e.g. replacement of thās with se.
ṇit: Causes vṛddhi for certain vowels.
pit: Causes anudātta accent on a pratyaya. A sārvadhātuka suffix not marked by p is treated as ṅit.
mit: If a replacement is marked with m, it is inserted after the last vowel of the sthānī.
śit: If a replacement is marked with ś, it replaces the entire sthānī. Generally, a pratyaya marked with ś can be called sārvadhātuka.
