Practice: Plurals

Add -en to most nouns. If the noun ends in a short vowel + single consonant, double the consonant first to preserve the short sound.

Nouns ending in a vowel (a, o, u, i, y) take -'s. The apostrophe prevents the vowel from merging.

Nouns with an unstressed final syllable ending in -er, -el, -en, -em, -aar take -s. These are typically 2-syllable words where adding -en would sound wrong.
