This one is slightly more interesting than a mere cognate as it is believed that the Proto-Indo-European speakers worshipped a sky god with the reconstructed name *Dyḗus ph₂tḗr ("sky-father") which is the ancestor of these (also Tyr and the like on the Germanic side). See:
https://en.wikipedia.org/wiki/*Dy%C4%93us
"*Dyēus is considered by scholars the most securely reconstructed deity of the Indo-European pantheon, as identical formulas referring to him can be found among the subsequent Indo-European languages and myths of the Vedic Indo-Aryans, Latins, Greeks, Phrygians, Messapians, Thracians, Illyrians, Albanians and Hittites."
What I find interesting is that the primary Turkic/Mongolic deity, Tengri, is also a sky father. There’s no shared genetic or linguistic ancestry there, just two different steppe nomad populations independently deifying the daylight sky the same way.
For example, 'to be' - French 'etre' (circumflex over the e indicates old 's' after the e), Marathi 'asane' (pronounced esnay)
'to go', German gehen, Marathi jana (when conjugated the j becomes hard)
'to give', french 'donner', Hindi 'danaa' (pronounced similarly)
'to mix', french 'melanger', Hind 'melaanaa'
Other non-obvious ones:
Vedas and Wisdom / Wit. Alternatively, Latin video (to see)
Dyaus-pitar and Jupiter, Zeus-pater
'that' in English is 'que' (that/what) in french and 'kya' (for what) or 'ki' (for that) in Hindi (pronounced similarly to French 'que').
English burden or 'to bear' and Hindi bhar (burden)
English 'ignite', Latin 'ignis' and Indic 'agni' (fire)
'Raja' and 'regal' or 'royal'
'Dental' and Hindi 'dant' (tooth)
Greek 'polis' and Indic 'pore' / 'pur' / 'puram' (the 'r' is pronounced like a soft l)
