Pre-Finno-Ugric substrate refers to substratum loanwords from unidentified non-Indo-European and non-Uralic languages that are found in various Finno-Ugric languages, most notably Sami. The presence of Pre-Finno-Ugric substrate in Sami languages was demonstrated by Ante Aikio. Janne Saarikivi points out that similar substrate words are present in Finnic languages as well, but in much smaller numbers. The proposed substrate influence in Finnic may have been related either by borrowing or a direct genetic relationship to the languages that influenced Saami.
Borrowing to Saami from Paleo-Laplandic probably still took place after the completion of the Great Saami Vowel Shift. Paleo-Laplandic likely became extinct about 1500 years ago.
The Nganasan language also has many substrate words from unknown extinct languages in the Taimyr peninsula.
