Plural and singular forms
General rules (detailed explanation RB pp 81-82):1. To make a plural form in English you add an -s to the noun (no apostrophes!!). There are multiple spelling irregularities!
2. There are certain nouns that do not change when used plural. (deer, sheep)
3. There are certain nouns that change differently when used plural. (women, children)
4. Some words are always plural/singular in English, but this differs from Dutch.
