szélességük

Szélesség is a Hungarian noun meaning width or breadth. Szélességük is the third-person plural possessive form, translating to "their width." In Hungarian, possessive suffixes attach to the noun to indicate ownership, and the suffix -ük marks possession by multiple possessor. The base word szélesség is formed with the abstract-noun suffix -ség from the adjective széles, meaning wide.

The form szélességük is used when referring to the widths of several items or subjects mentioned in the preceding context. For example: A polcok szélességük 40–60 cm között változik. (The shelves’ widths vary between 40 and 60 cm.) Another example: Az ablakok szélességük 70–90 cm között alakult ki. (The windows’ widths range from 70 to 90 cm.) In such sentences, szélességük functions as a noun phrase meaning “their widths.”

When the possessor is singular, a different form is used: szélessége. For instance: Az ablak szélessége 60 cm. (The width of the window is 60 cm.) This contrast shows how Hungarian marks possession and number in noun phrases: szélességük for plural possessors, szélessége for a singular possessor.

Etymology and usage notes: szélesség comes from széles (wide) with the abstract-noun suffix -ség, forming a concept of horizontal extent. The possessive suffixes follow standard Hungarian vowel harmony and attach to the noun stem, producing forms such as szélességük (their width) or szélessége (its/your width, depending on context). The term is common in technical, architectural, and design descriptions, as well as in everyday measurement discussions.
