hundruðum
hundruðum is an Icelandic word. It is the dative plural form of the word hundrað, which means "hundred." Therefore, hundruðum translates to "by hundreds" or "with hundreds." This form is used when indicating that something is done or achieved in quantities of hundreds, or when referring to something being associated with or possessed by hundreds of entities. For example, a sentence might describe a situation where an event occurred "hundruðum manna" meaning "by hundreds of men." The grammatical case, dative, is crucial in Icelandic for indicating the role of a noun or pronoun in a sentence, and hundruðum specifically signals this plural, numerous quantity in a certain grammatical context. It is not a standalone noun or concept but rather a grammatical inflection of the numeral.
