Substrateilta

Substrateilta is a Finnish inflected form that means “from substrates.” It is the elative plural form of the borrowed noun substraatti (substrate) and is used in scientific and technical Finnish to indicate origin or source when several substrates are involved.

The term appears across disciplines where materials or samples originate from different substrate types, such as biology, microbiology, geology, chemistry, and materials science. It helps specify provenance in descriptions of experiments, analyses, and datasets, for example when comparing results from multiple substrate types.

Examples of usage include: Näytteet otettiin substraateilta X, Y ja Z. Substraateilta peräisin olevat mikrobit eristettiin laboratoriossa. In these contexts, substrateilta functions as a grammatical device rather than as a standalone concept; it relies on a base term such as substraatti or the English loanword substrate and is governed by Finnish case and number rules.

Relation to other terms: substraatti is the corresponding noun for the physical material on which processes occur, while elatiivi (elative) describes origin. Substrateilta may appear in research papers, methods sections, and data descriptions to compactly indicate that items come from multiple substrates.
