erissä

Erissä is a Finnish term used to describe something that is delivered, paid, or completed in multiple parts rather than in a single piece. It is commonly found in business, logistics, and consumer finance contexts, where schedules or contracts specify that goods, payments, or tasks will occur in separate portions over time. In translations, erissä is often rendered as “in installments” or “in batches.”

The word derives from the noun erä, meaning a batch, lot, or set. The form erissä is the inessive plural of erä, signifying “in batches” or “in installments.” The phrase is flexible enough to modify verbs and clauses, as in arrangements that are divided into predefined parts.

Usage and examples:

- Lainan takaisinmaksu tapahtuu erissä, esimerkiksi kuuden kuukauden jaksoissa. (Repayment of the loan occurs in installments, over six-month periods.)

- Tilaus toimitetaan erissä. (The order will be delivered in batches.)

- Hankkeelle on laadittu eräkohtainen aikataulu, jossa osa vaiheista suoritetaan erissä. (A batch-based schedule has been prepared for the project, with parts completed in installments.)

Nuances and alternatives:

- Erissä emphasizes division over time and the sequential nature of parts, as opposed to a single, lump-sum action.

- Alternatives include kerrallaan (one at a time) or osamaksu (installment payments) depending on the context and emphasis.
