In linguistics, cognates are words that have a common etymological origin.
For instance today’s Romance languages (Spanish, French, Italian, Romanian, Catalan, etc.) all share the same “parent” language, the Latin. And therefore these languages have a lot of cognates.
Starting from October 2019, there are verb cognates on the Verbix website. On the cognate pages you can check out how the Indicative present looks like in different Romance languages.
As can be seen, sometimes the differences are relatively big. And what’s more, sometimes the meaning of the word may have changes.
