Word forms

Word forms provide declension for words in SEO text.

Purpose

Some languages require declension by case:

Case	Example
Nominative	phone
Genitive	phone's
Dative	(to) phone
Accusative	phone
Instrumental	(with) phone
Prepositional	(about) phone

Word forms table

Column	Description
Word	Nominative form
Genitive	Genitive form
Dative	Dative form
Accusative	Accusative form
Instrumental	Instrumental form
Prepositional	Prepositional form
Plural	Plural form

Creating a word form

1. Click "Create"

2. Fill in the forms

Field	Example
Word	phone
Genitive	phone's
Dative	phone
Accusative	phone
Instrumental	phone
Prepositional	phone
Plural	phones

3. Save

Use in SEO templates

Case modifiers

Modifier	Case	Example
`	nominative`	Nominative
`	genitive`	Genitive
`	dative`	Dative
`	accusative`	Accusative
`	instrumental`	Instrumental
`	prepositional`	Prepositional
`	plural`	Plural

Examples

Title template:

Buy {$filters.vendor|accusative}

Result:

• Input: Samsung
• Word form: accusative = Samsung
• Result: Buy Samsung

Description template:

Wide selection of {$filters.vendor|genitive}. Delivery.

Auto declension

If a word form is not in the database, the system may:

1. Use the word unchanged
2. Apply basic language rules (if enabled)

Programmatic access

$mfilter = $modx->services->get('mfilter');
$wordForms = $mfilter->getWordFormsManager();

// Get form
$genitive = $wordForms->getForm('phone', 'genitive');
// 'phone\'s'

// Check existence
$exists = $wordForms->hasWord('phone');

// Add word form
$wordForms->add([
    'word' => 'laptop',
    'genitive' => 'laptop\'s',
    'dative' => 'laptop',
    'accusative' => 'laptop',
    'instrumental' => 'laptop',
    'prepositional' => 'laptop',
    'plural' => 'laptops'
]);

Tips

1. Add brands — Samsung, Apple, Xiaomi often don't decline
2. Add categories — phone, tablet, laptop
3. Check output — review generated text
4. Use import — for large word lists

Common cases

Invariable words

For foreign brands, use the same form for all cases:

Field	Value
Word	Apple
Genitive	Apple
Dative	Apple
...	Apple

Words with alternation

Field	Value
Word	day
Genitive	day's
Dative	day
