stiletto

The word stiletto has two main meanings, linking fashion with an older kind of weapon. Today, it is most often used for a high-heeled shoe with a very thin heel that tapers to a point like a needle. The heel is what defines this kind of shoe, even if the front shape can vary. In modern use, stilettos are often connected with formal wear, glamour, bold style, and the challenge of walking gracefully in very narrow heels.

The older meaning comes from the original stiletto, a narrow dagger associated with Italy from the Renaissance onward. It was made for thrusting rather than slashing, and its thin blade could slip through heavy clothing or small gaps in armor. Because of that design, the word came to suggest sharpness, precision, and a slender form.

The connection between the dagger and the shoe is their shared needle-like shape. When this footwear style became popular in the mid-20th century, the same word was used for heels that looked long, thin, and sharp. So depending on the context, stiletto can mean either a stylish shoe or a slim dagger. You might say, "She crossed the room in black stilettos," or "The museum displayed a jeweled stiletto from Renaissance Italy."
