Ƒ

Lowercase F with a hook in regular type on the left and in italic on the right, the florin sign is always in italic.

The letter F with a hook (majuscule Ƒ, minuscule: ƒ) is a letter of the Latin script, based on the italic form of f; or on its regular form with a descender hook added. A very similar-looking letter, ⟨ʄ⟩ (a dotless j with a hook and a horizontal stroke), is used in the IPA for a voiced palatal implosive.

Regular[]

Ƒ is used in writing the Ewe language in a straight form to represent the sound [ɸ], as distinct from the letter F, which represents an [f].

Italic[]

The minuscule italic ƒ, also called the florin sign, is used as a symbol for several currencies, including the former Dutch guilder, the Aruban florin, and the Netherlands Antillean guilder. It can be found as italic in non-italic fonts.

The italic ƒ has been used to denote mathematical functions,^[1] or to indicate aperture in photography (e.g. ƒ/2.8) in place of the more common italic f (in serif fonts) or oblique f (in sans-serif fonts).^{[citation needed]} It can be represented with U+1D453
