What does urticating mean?
Urticating means causing an itchy or stinging irritation, most commonly in reference to the tiny hairs of nettles and similar plants. The word also describes animals, such as certain caterpillars, whose hairs or spines can produce a painful rash when touched. In phrases such as “urticating hairs,” it functions as an adjective, while the less common verbal use means to sting or irritate in this way. The term has a formal, scientific tone and is especially associated with descriptions of plants and animals whose defenses cause a nettle-like reaction. It is useful when the source of an irritation needs to be identified precisely: an itchy patch might be described as caused by an urticating plant rather than merely an irritating substance. Although uncommon in everyday conversation, the word captures the distinctive action of nettles and similarly armed organisms with greater accuracy than the general word “irritating.”
Causing itching or stinging irritation, especially by means of nettle-like hairs, spines, or similar structures.
"The plant's urticating hairs can cause a severe skin reaction."
Commonly used attributively in botanical and zoological descriptions.
Stinging or causing an itching irritation.
"Some caterpillars urticate defensively when disturbed."
This is the present participle of the rare verb “urticate”; it is less common than the adjectival use.
Nettle hairs are tiny chemical weapons: their urticating sting can turn a casual brush with a plant into an intensely itchy lesson.

Etymology of urticating
“Urticating” derives from the English verb “urticate,” which comes from Latin urticare, “to sting with nettles.” Latin urtica means “nettle,” and the family also includes English words such as “urticant,” “urtication,” and “urticaria,” the medical term for nettle rash. The modern participial form “urticating” follows the regular English pattern of adding “-ing” to the verb.
