What does itch mean?
An itch is an uncomfortable sensation in the skin, often caused by irritation, dryness, insects, or a material such as wool. The related verb means to experience this sensation or, in informal usage, to feel a strong urge to do something. In phrases such as “have an itch to travel,” the word describes a keen desire rather than a physical symptom. This figurative use is widespread in everyday British and American English and often carries a playful tone. Although scratching may temporarily relieve a physical itch, it can worsen some conditions, so the word is useful in both medical and conversational contexts. The expression “relieve an itch” is especially common, while “satisfy an itch” can refer either to scratching or to fulfilling a strong desire.
An uncomfortable tingling or itching sensation, especially one that prompts scratching; figuratively, an informal strong desire to do something.
"The bug bite caused an itch that lasted all evening."
The figurative sense is informal and commonly used with “an itch to” followed by an infinitive.
To experience an itching sensation or, informally, to feel a strong urge to do something.
"My hands itched after touching the stinging nettle."
The informal figurative use often appears in constructions such as “itch to travel” or “itch to know.”
Used when referring to multiple sensations or desires, though the plural is less common than the singular in ordinary conversation.
"The warm weather brought on a few unexpected itches."
The word itch carries both a physical sensation and a figurative urge, as in having an itch to travel.
