Text Dictionary Rules

Dictionary Definition Format

If you want to use your own dictionary, these are the syntax options you can use. This is the general syntax:

word [P:PRIMARY_POS,SECONDARY_POS ; A:ATTRIBUTE1, ATTRIBUE2 ; Pr:PRONUNCATION ]

POS

P is used for defining dictionary item's Part of Speech tag. There are Primary and Secondary tags available. Some Primary POS values are

Noun, Adj, Verb, Adv, Pron, Conj, Det, Postp, Interj, Dup

For nouns, usually you do not need to add a P:Noun property. System assumes words that does not end with mek or mak a noun. Such as:

kalem --> Assumes "kalem [P:Noun]"

If a word ends with mek or mak system assumes that word is a verb.

okumak --> Assumes "okumak [P:Verb]"

For some nouns that ends with mak or mek, P:Noun property must be written. Such as

çomak [P:Noun]
yumak [P:Noun]

If first letter is capital, it is assumed a proper noun.

Ankara --> Assumes "Ankara [P:Noun, Prop]"

For abbreviations, Abbrv secondary Pos value must be written.

Tdk [P:Abbrv] --> Assumes "Tdk [P:Noun, Abbrv]"

For all other types, Pos value must be written.

ekşi [P:Adj]
ve [P:Conj]
bu [P:Pron, Demons]  --> Demonstrative Pronoun

However, defining pronouns externally may not work well because most pronoun suffix rules are handled in the code.

There are primary and secondary POS values.

Attributes

Voicing and NoVoicing In Turkish, if last letter of a word or suffix is a stop consonant (tr: süreksiz sert sessiz), and a suffix that starts with a vowel is appended to that word, last letter changes. This is called voicing. Changes are p-b, ç-c, k-ğ, t-d, g-ğ. Such as kitap → kitab-a, pabuç → pabuc-u, cocuk → cocuğ-a, hasat → hasad-ı

It also applies to some verbs: et→ed-ecek. But for verb roots, only ‘t’ endings are voiced. And most suffixes: elma-cık→elma-cığ-ı, yap-acak→yap-acağ-ım.

When a word ends with ‘nk‘, then ‘k’ changes to ‘g’ instead of ‘ğ’. Such as cenk → ceng-e, çelenk → çeleng-i

For some loan words, g-ğ change occurs. psikolog → psikoloğ-a

Usually if the word has only one syllable, rule does not apply. Such as turp → turp-u, kat → kat-a, kek → kek-e, küp → küp-üm. But this rule has some exceptions as well: harp → harb-e

Some multi syllable words also do not obey this rule. Such as taksirat → taksirat-ı, kapat → kapat-ın

For making a dictionary entry, you do not need to add Voicing attribute to nouns or adjectives that ends voiceless consonants. For example for word kitap System automatically assumes this is a noun and because it ends with p it has Voicing attribute. But for single syllable words, system automatically add NoVoicing attribute.

kitap --> assumes "kitap [P:Noun; A:Voicing]". Allows "kitaba"
top   --> assumes "top [P:Noun; A:NoVoicing]". Prevents "toba"

If default behavior is wrong for a word, "Voicing" or "NoVoicing" attributes must be written. For example,

bulut [A:NoVoicing]  --> to prevent `buludu`
turp [A:Voicing]     --> to allow `turbu`

InverseHarmony : For some loan words, suffix vowel harmony rules does not apply. This usually happens in some loan words. Such as saat-ler and alkol-ü

saat [A:InverseHarmony,NoVoicing]

Doubling When a suffix that starts with a vowel is added to some words, last letter is doubled. Such as hat → hat-tı. If last letter is also changed by the appended suffix, transformed letter is repeated. Such as ret → red-di

hat [A:Doubling] // no need to add NoVoicing because it is single syllable.

LastVowelDrop Last vowel before the last consonant drops in some words when a suffix starting with a vowel is appended. ağız → ağz-a, burun → burn-um, zehir → zehr-e.

Some words have this property optionally. Both omuz → omuz-a, omz-a are valid. Sometimes different meaning of the words effect the outcome such as oğul-u and oğl-u. In first case "oğul" means "group of bees", second means "son".

Some verbs obeys this rule. kavur → kavr-ul. But it only happens for passive suffix. It does not apply to other suffixes. Such as kavur→kavur-acak, not kavur-kavracak

When a vowel is dropped, the form of the suffix to be appended is determined by the original form of the word, not the form after vowel is dropped. Such as nakit → nakd-e, lütuf → lütf-un.

If we were to apply the vowel harmony rule after the vowel is dropped, it would be nakit → nakd-a and lütuf → lütf-ün, which are not correct.

For making a dictionary entry:

ağız [A:LastVowelDrop] kavurmak [A:LastVowelDrop]

CompoundP3sg

This is for marking compound words that ends with third person possesive suffix P3sg [+sI]. Such as aşevi, balkabağı, zeytinyağı.

These compound words already contains a suffix so their handling is different than other words. For example some suffixes changes the for of the root. Such as zeytinyağı → zeytinyağ-lar-ı atkuyruğu → atkuyruklu

Dictionary entries are a little different. You need to specify root forms of the words that builds the compound word.

aşevi [A:CompoundP3sg; Roots:aş-ev]

**Aorist_I and Aorist_A

Generally Present tense (Aorist) suffix has the form [Ir]; such as gel-ir, bul-ur, kapat-ır. But for most verbs with single syllable and compound verbs it forms as [Ar]. Such as yap-ar, yet-er, hapsed-er. There are exceptions for this case, such as "var-ır". Below two represents the attributes for clearing the ambiguity. These attributes does not modify the root form.

System automatically assumes a verb has A:Aorist_I form for multi syllable verbs and Aorist_I form for single syllable verb roots. Such as

bulmak    // "bul-ur"
yapmak    // "yap-ar"

If a verb does not obey the rule, related attribute should be written.

affetmek [A:Voicing, Aorist_A]  // "affeder", not "affedir"
bilmek [A:Aorist_I] // "bilir", not  "biler"
