Terttuja

Terttuja is a Finnish-language term that can function as a plural reference to people named Terttu. It is not a standard lexical item with a fixed, separate meaning beyond indicating more than one bearer of the given name. The form arises from the common practice in Finnish of using proper names in a collective, informal sense when several individuals share the same name.

The given name Terttu is Finnish and is traditionally a feminine name. It is considered a historical form of a name related to Teresa or Therese and has appeared in Finnish literature and public life for many decades. Because terttuja is not a formally defined noun, its usage is limited to contexts where speakers or writers refer to multiple people named Terttu, typically in informal speech, family records, or anecdotal storytelling.

In formal writing, it is usual to identify individuals by full names or initials (for example, Terttu A. and Terttu B.) rather than employing the collective term terttuja. The term does not denote a distinct organization, concept, or widely recognized entity in standard Finnish reference works.
