XXVII

XXVII is the Roman numeral for the number 27. It is formed by adding the values of X (10) + X (10) + V (5) + I (1) + I (1), yielding 27; the standard written form is XXVII. In the traditional Roman numeral system, numbers are written by combining symbols I, V, X, L, C, D, and M with additive notation, while subtractive forms (such as IV for 4 or IX for 9) are used for other numbers.

XXVII is used to denote the 27th item in a sequence, such as chapters, volumes, or lists, and appears in contexts where Roman numerals are preserved or preferred for stylistic reasons. It can also appear in inscriptions and dated records that use Roman numerals, or as a numeral marker in historical or academic writing.

In contemporary usage, XXVII may appear as a stylistic or branding element in titles, logos, media, or fashion, where the numeral represents the value 27 without implying mathematical operations. It is one of several ways to express the ordinal 27, though ordinal forms are usually indicated with a suffix (27th) in modern English.
