estimoiattiin

Estimoiattiin is a Finnish verb form meaning “were estimated.” It is the passive past tense of estimioida, a verb meaning to estimate. The form is used to indicate that an estimation was performed, often by an unspecified agent.

Formation is based on the stem estimoi- plus the infix -tti- and the passive past ending -in, yielding estimoiattiin. This pattern is typical for Finnish verbs in the -oida class when forming the past passive. The double consonant is a normal result of infixation and vowel harmony in Finnish phonology.

Usage of estimoiattiin occurs in formal and technical Finnish, including statistics, budgeting, research reporting, and journalism. It is used to convey that a figure or assessment was produced through an estimation process rather than measured directly, and it allows the agent of the estimation to be unnamed or generalized.

Examples include: “Kustannukset estimoiattiin kolmen kuukauden kuluessa.” (The costs were estimated within three months.) “Arviot estimoiattiin aiempien tutkimustulosten perusteella.” (The estimates were made based on previous study results.) In many contexts, arviot (estimates) or arviointi (evaluation) may be preferred, but estimoiattiin remains common in technical prose and statistical reporting.

Etymology note: estimioida is a Finnish loanword formed with the -oida suffix, typical for verbs meaning “to do X,” with the origin traceable to broader estimation terminology in Swedish or English. See also estimointi (estimation), arviointi (evaluation).
