substratum

Usage Note

Sustrato is used both in linguistics (the language a conquered population spoke before adopting a new tongue) and in geology/biology (a layer beneath the surface). In linguistics, scholars speak of the sustrato ibérico that influenced early Latin in Spain. The biological sense refers to the medium on which an organism grows, like the soil or a culture plate.

Examples

"El latín conservó rasgos del sustrato celta."
