peremeesliigile

Peremeesliigile is an Estonian term used in biology to denote the host species in host–parasite and related biological contexts. It refers to the species that a parasite, pathogen, or symbiont relies on for development, reproduction, or survival. The form peremeesliigile is the allative case of peremeesliik (host species) and is used in Estonian to express direction toward or association with the host, for example when describing host range or host specificity.

In practice, the term helps distinguish the functional role of a species as a host from its taxonomic identity. The concept corresponds to the English expression “host species” and is common in discussions of host specificity, transmission, and life cycles in ecological and parasitological literature. Related forms include peremeesliik (the host species in a more general or nominative sense) and peremeesliigi (the genitive form “of the host species”).

The term is primarily found in Estonian-language scientific texts and glossaries dealing with parasitology, epidemiology, and ecological interactions.
