Grammar rule for a singular container of plural items
September 2, 2020 11:18 AM Subscribe
In English we have terms like "pencil case", "shoe box", "tool box", "cocktail bar", where we use the singular even though the contents are assumed to be plural, i.e. more than one pencil, shoe, tool or cocktail is intended to be inside. Is there a name for this rule and is it ungrammatical to break it, e.g. "bookmarks bar".
