# Fix the i18next _zero plural suffix not rendering

## TL;DR

English simply has no zero plural form, so i18next correctly skips your _zero key and falls back to _other. Check what Intl.PluralRules says for your locale before adding suffixes. For English, put the zero-case copy in _other or handle count 0 as a separate key.

## The error

```text
t('items', {count: 0}) renders "0 items" from items_other
expected the items_zero string, which exists in the JSON
```

## Fix it

### Step 1: Ask the platform which plural form zero takes

```bash
node -e "console.log(new Intl.PluralRules('en').select(0), new Intl.PluralRules('ar').select(0))"
```

Expected: en prints other, ar prints zero. That tells you which suffix each locale will ever use.

### Step 2: List the suffixes your JSON actually defines

```bash
node -e "const j=require('./public/locales/en/translation.json'); console.log(Object.keys(j).filter(k=>k.startsWith('items')))"
```

Expected: You see items, items_other, items_zero or whatever is really there.

### Step 3: Move the zero copy where English will find it

```bash
node -e "console.log('for en: put zero-case wording in items_other, or branch on count===0 in code')"
```

Expected: count 0 now renders the wording you intended.

### Step 4: Keep _zero only for locales that have a zero form

```bash
node -e "console.log(new Intl.PluralRules('ar').select(0))"
```

Expected: Arabic keeps its zero form, English stops pretending to have one.

## When to use this

- A _zero key exists but count 0 renders the _other string
- You are adding plural suffixes and want to know which ones a locale supports

## When NOT to use this

- You need an exact-count special case, use a separate key or branch in code
- The plural logic itself is wrong, check the count value you pass

## Tool and version compatibility

- i18next v21 through v25, JSON v4 plural format
- Intl.PluralRules in all modern browsers and Node 13+

## Variant phrasings

### _one not used for French zero

Same root cause. French treats 0 as one, so items_one renders for count 0. That is correct CLDR behavior.

### Russian few/many forms ignored

You probably defined only _one and _other. Russian needs one, few, many, and other. Add all four.

## Why it happens

i18next v4 resolves plural suffixes through Intl.PluralRules, which implements the CLDR rules per locale. English has only one and other, so _zero can never match in English no matter what your JSON says. Arabic, Latvian, and a few others genuinely have a zero category.

## Edge cases

- JSON v3 used key_plural, v4 uses CLDR suffixes, mixing them breaks resolution
- ordinal plurals are a separate lookup, _ordinal suffixes do not mix with cardinal ones
- Some locales change rules by script or region, test with the exact BCP47 tag you ship
