Let's say your multilingual site supports two languages, English and Polish. Create a translation table for each language in the `i18n` directory.
```
i18n/
├── en.toml
└── pl.toml
```
The translation tables can contain both:
- Simple translations
- Translations with pluralization
The Unicode [CLDR Plural Rules chart] describes the pluralization categories for each language.
[CLDR Plural Rules chart]: https://www.unicode.org/cldr/charts/43/supplemental/language_plural_rules.html
The English translation table:
{{< code-toggle file=i18n/en copy=false >}}
# simple translations
privacy = 'privacy'
security = 'security'
# translations with pluralization
[day]
one = 'day'
other = 'days'
[day_with_count]
one = '{{ . }} day'
other = '{{ . }} days'
{{< /code-toggle >}}
The Polish translation table:
{{< code-toggle file=i18n/pl copy=false >}}
# simple translations
privacy = 'prywatność'
security = 'bezpieczeństwo'
# translations with pluralization
[day]
one = 'miesiąc'
few = 'miesiące'
many = 'miesięcy'
other = 'miesiąca'
[day_with_count]
one = '{{ . }} miesiąc'
few = '{{ . }} miesiące'
many = '{{ . }} miesięcy'
other = '{{ . }} miesiąca'
{{< /code-toggle >}}
{{% note %}}
The examples below use the `T` alias for brevity.
{{% /note %}}
When viewing the English language site:
```go-html-template
{{ T "privacy" }} → privacy
{{ T "security" }} → security
{{ T "day" 0 }} → days
{{ T "day" 1 }} → day
{{ T "day" 2 }} → days
{{ T "day" 5 }} → days
{{ T "day_with_count" 0 }} → 0 days
{{ T "day_with_count" 1 }} → 1 day
{{ T "day_with_count" 2 }} → 2 days
{{ T "day_with_count" 5 }} → 5 days
````
When viewing the Polish language site:
```go-html-template
{{ T "privacy" }} → prywatność
{{ T "security" }} → bezpieczeństwo
{{ T "day" 0 }} → miesięcy
{{ T "day" 1 }} → miesiąc
{{ T "day" 2 }} → miesiące
{{ T "day" 5 }} → miesięcy
{{ T "day_with_count" 0 }} → 0 miesięcy
{{ T "day_with_count" 1 }} → 1 miesiąc
{{ T "day_with_count" 2 }} → 2 miesiące
{{ T "day_with_count" 5 }} → 5 miesięcy
```
In the pluralization examples above, we passed an integer in context (the second argument). You can also pass a map in context, creating a `count` key to control pluralization.
Translation table:
{{< code-toggle file=i18n/en copy=false >}}
[age]
one = '{{ .name }} is {{ .count }} year old.'
other = '{{ .name }} is {{ .count }} years old.'
{{< /code-toggle >}}
Template:
```go-html-template
{{ T "age" (dict "name" "Will" "count" 1) }} → Will is 1 year old.
{{ T "age" (dict "name" "John" "count" 3) }} → John is 3 years old.
```
