Pronunciation: [ɪnˈɜːmiz] (IPA) 
The word "Inermis" is commonly used in taxonomy to describe a species that lacks spines or weapons. Its spelling is based on Latin, where "in-" means "not" and "ermis" comes from "armus" which means "arm" or "weapon". In IPA phonetic transcription, "Inermis" is pronounced as /ɪˈnɜːmɪs/ with emphasis on the second syllable. The word is often misspelled as "Inermus" due to confusion with the Latin word "inermus" which means "defenseless".
Inermis is a Latin adjective that can be loosely translated as "unarmed" or "defenseless". Originating from the word "inermis", meaning "without weapons", it is often used in scientific and taxonomic terminology to describe certain species or organisms that lack any form of physical weaponry, defensive structures, or protective mechanisms.
In biology, "inermis" is commonly employed to classify various organisms, such as plants, invertebrates, or even mammals, that do not possess any noticeable offensive or defensive features. For instance, it may refer to a species of plant that lacks thorns, prickles, or spines, rendering it incapable of causing harm or defending itself against predators. Similarly, "inermis" may describe an animal that lacks claws, fangs, or venomous appendages.
Beyond the realm of biology, "inermis" can extend to describe a broader sense of vulnerability or defenselessness in different contexts. It may be metaphorically applied to human beings, institutions, or ideas that lack power, protection, or resources, leaving them exposed and susceptible to harm or exploitation.
Consequently, "inermis" serves as an adjective that highlights the absence of weaponry, physical defenses, or protective measures in a wide range of organisms or situations, emphasizing their inherent vulnerability or defenselessness.
In bot., unarmed; without prickles or thorns.

The word "Inermis" is Latin in origin. It is derived from the combination of two Latin roots: "in", meaning "not", and "armis", which means "armed" or "weapons" in Latin. Therefore, "inermis" can be understood as "not armed" or "unarmed" in English.
