Toksilise

Toksilise is a grammatical form of the Estonian adjective toksiline, meaning "toxic." In Estonian, adjectives decline to agree with the noun they modify, so toksilise appears in inflected forms rather than as a standalone dictionary entry. The form toksilise specifically corresponds to genitive singular (and appears in other cases in reduced or compound phrases).

Etymology and usage: The Estonian word toksiline is borrowed from the same Indo-European roots that produced words for poison and toxin in many languages, tracing back to Greek toxikon and Latin toxicum. In Estonian, toksiline is used to describe substances, effects, or conditions that are poisonous or harmful to living organisms. The genitive form toksilise is common in phrases that express possession, measurement, or description within a clause.

Examples: Common constructions include toksilise toimega (with a toxic effect) and toksilise aine mõju (the effect of a toxic substance). The same stem appears across compounds such as toksilise aine või toksilise toimega ravimid, illustrating how the adjective agrees with the noun in different cases and numbers.

Grammatical notes: As with other Estonian adjectives, toksiline forms combine with nouns to create descriptive phrases. The grammatically required ending depends on the noun’s case and number; toksilise is one such ending used in genitive singular and in related inflected forms within multi-word phrases.
