Anderhalf

Anderhalf is a Dutch numeric expression that denotes the quantity one and a half, i.e., 1.5. It is used in everyday language to express approximate measures, durations, and amounts, such as time, volume, or length. The term appears in both spoken and written Dutch and is understood across Dutch-speaking regions, including the Netherlands and Flanders.

In spelling, anderhalf can appear as two forms: anderhalf and anderhalve. The form chosen often depends on the noun that follows or on regional style. Common examples include anderhalf uur (one and a half hours), anderhalve liter melk (one and a half liters of milk). When the quantity stands with a following noun, anderhalve is frequently used; when the quantity is used more independently, anderhalf is common. Both forms are widely accepted in standard Dutch.

Usage notes: anderhalf is primarily used for approximate quantities and durations in everyday speech and writing. In formal mathematics or precise technical writing, numbers are typically presented numerically (1.5) or spelled out in longer phrases, rather than relying on the colloquial anderhalf construction. The term is a standard part of Dutch numeracy and appears in education, media, and commerce.
