Final answer:
A given noun typically has an immutable gender, though it should be noted that English nouns themselves do not have gender as it is defined in other languages. The term 'gender' in English primarily applies to pronouns and people, rather than to nouns.
Step-by-step explanation:
With few exceptions, any given noun has only one gender, and it will never change. A noun can be defined as a word that represents a person, place, thing, or idea. Generic nouns and most indefinite pronouns are singular in meaning. Proper nouns, which represent a specific person, historical event, or other named entity, are always capitalized. It is interesting to note that while the concept of gender does apply in many languages, English nouns do not have gender in the way that nouns in some other languages like French or Spanish do. In English, the gender of nouns is generally not marked or changed.
