# Fix plural selectordinal error on French one vs other

## TL;DR

French ordinals treat only 1 as one, everything else is other, so write your selectordinal cases to match. If your message lists one, two, few like English, French picks wrong for 2 and 3. Check Intl.PluralRules with ordinal true for fr, then keep just the cases French can actually select.

## The error

```text
French ordinal for 2 renders the English-style "two" case
{n, selectordinal, one {#er} two {#e} other {#e}} picks wrong in fr
```

## Fix it

### Step 1: Check what French ordinals actually select

```bash
node -e "for(const n of [1,2,3]) console.log(n, new Intl.PluralRules('fr',{type:'ordinal'}).select(n))"
```

Expected: fr prints one for 1 and other for 2 and 3.

### Step 2: Trim the message to the cases French uses

```bash
node -e "console.log('for fr: {n, selectordinal, one {#er} other {#e}} -- drop the two case')"
```

Expected: The message matches French ordinal rules.

### Step 3: Keep per-locale messages where ordinals differ

```bash
node -e "console.log('translators should adapt the case list per language, not translate the English cases literally')"
```

Expected: Each locale has the cases its rules need.

### Step 4: Render 1st, 2nd, 3rd in French and confirm

```bash
node -e "console.log('1 to 1er, 2 to 2e, 3 to 3e')"
```

Expected: Ordinals render correctly.

## When to use this

- French ordinals pick the wrong selectordinal case
- Ordinal cases were copied from English

## When NOT to use this

- Cardinal plurals in French, those follow different rules
- The ordinal logic is right but the suffix text is wrong, fix the copy

## Tool and version compatibility

- ICU selectordinal, Intl.PluralRules with type ordinal
- French ordinal rules: 1 is one, masculine 1er

## Variant phrasings

### Spanish ordinals

Spanish ordinals are simpler, usually just other with º. Same per-locale adaptation applies.

### English ordinals as reference

English needs one, two, few, other. The point is each language gets its own case list.

## Why it happens

Selectordinal uses the locale's ordinal plural rules, not its cardinal ones. French ordinals only distinguish 1er from the rest, so English-style one/two/few cases never match in French and counts fall through to unexpected cases.

## Edge cases

- Gender matters in French ordinals, 1er vs 1re, the message may need a select on gender too
- Translators must rewrite the case list, not just the words
- Test ordinals 1 through 5 minimum, edge counts expose bad case lists
